Weaponizing Terrain

[Vysii 45]

In a corner of the Basking Turtle tavern in Beznov, Adria, a half-conscious Ahren Jaeger fought what was perhaps his hardest battle in years: the struggle to finish the next of many essays. Dark bags formed beneath bloodshot eyes. Veins pulsed all over his brain. His heart thumped against his ribcage. His body swayed back and forth as the weary and ageing siege engineer struggled to stay upright, anchored to his table only by the marginal pressure his now-smoking quill still exerted on the paper. All he could do to stave off collapse was take a swig from his nth Euler Max bottle and pray he’d still be conscious by the end of the current paragraph. It was not the first he drank, nor would it be anywhere near the last.

It was clear just from the clusters of empty Euler Max bottles littering his table that he spent no few consecutive all-nighters writing this essay. He wanted it done as soon as possible. But at the same time, he put off its completion for far too long. He lost count of how many energy drinks he poured down his gullet in the process of writing the essay. But it was a high-enough number to convince him that sleep deprivation and liver failure would probably kill him long before any Spook could run him through. But so long as his efforts ended up helping his fellow Descendants in some meaningful way, then it all would have been worth it.

An indeterminate amount of Euler Maxes, whale steaks, and salted wyvern jerky later, Ahren would publish the following essay. He would later travel to Nevaehlen and personally distribute copies to the local Greenblades and any other allies involved in the Vale’s defence before finally passing out at the bottom of a sinkhole somewhere in the city.

Ahren needed all the energy he could muster. For he had a lot more work to do but very little time to do it.

On the defence of the Vale
Part Two: Weaponizing terrain

Preface

My name is Ahren Jaeger, a siege engineer of Adria. In this turbulent era where Darkspawn run rampant across the world, my backstory is far from unique. Long-story-short: Darkspawn toppled the walls of my hometown and ate my mother. The scene still haunts me nearly four decades later. Today, Darkspawn continue to sow tragedy and chaos wherever their unholy ilk are permitted to fester, stamping down on Descendantkind’s freedom to thrive and prosper in peace. I pray every day that good Descendants will emerge victorious in the struggle against evil, but we can’t expect God to do all the work. It has thus become my mission to exterminate the Darkspawn menace from this world, or at least help pave the way for those that will.

As of the time of this essay’s publishing, a powerful Darkspawn entity known as the Harrower has enthralled the tribes of Ailmere and set out on a warpath against all of Descendantkind. One of the realms he’s currently targeting is the Vale of Nevaehlen. In response to a request for help, I deployed to the Vale as part of a small military advisory team led by Cathan, one of Aevos’s foremost experts on combating Darkspawn. Simply put, our goal is to help the Valefolk defend themselves against the Harrower. I haven’t known the people of Vale for long, but, in my book, they have proven to be good people. They do not deserve to become puppet-slaves like the Ailmerian tribes, who now exist only as walking blood sacrifices. I wish only for the Valefolk to live happily in peace. Cathan and I have been helping the Valefolk prepare against the Harrower for just over three years now, and I’m happy to report they are making good progress.

I also noticed after publishing my previous essay that the On the defence of the Vale series’ readership grew beyond the Vale. So with this expanded readerbase in mind, going forward I will mainly aim to give general tactical advice while using the Harrower War and the Vale as primary examples to help illustrate my points.

This essay is the second part of my On the defence of the Vale series. This, along with future entries, will compile a number of ideas brought up in discussions by myself, Cathan, the Valefolk, and their allies on how the Vale’s terrain can be weaponized to optimal and devastating effect against potential invaders. If at least the important ideas get implemented, Nevaehlen is sure to become a veritable bulwark against the Shadowtide along with any other threat that dares threaten its people. I sincerely hope this helps.

Weaponizing terrain

The Vale of Nevaehlen benefits from some of the most defensible natural terrain in Aevos. It sits on a lightly forested plateau atop a mountainous island separated from the mainland by a deep, wide river and a near-complete ring of steep cliffs. Geography like this should put off all but the most creative, well-prepared, and determined invaders. But of course, as history keeps proving time and time again, deterrence never guarantees lasting peace; war always breaks out sooner or later. And when that happens, the Vale’s natural geography will not drive out an attacking force by itself; Nevaehlen’s Greenblades will still need to stand and fight. The enemy will likely bring overwhelming numbers of manpower and equipment to balance out the Valefolks’ control of key terrain. Optimal use of the island's terrain, both natural and man-made, will prove key in winning against such overwhelming odds.

‘Terrain’ is defined as an area of land when considering its features. For example: a flat and mostly empty mountain plateau can be described as flat terrain, heavy rainfall can turn vast areas of soil into muddy (and sometimes even impassable) terrain, and the more heavily built-up areas of a city can be described as dense urban terrain. The terrain can play a big role in deciding the course and outcomes of battles, campaigns, and even entire wars. It determines how an army can move its troops, their equipment, and their supplies through an area. It determines how easily troops can capture and hold an area. It determines how a battle may be fought in an area all the way down to the thought process and actions of individual soldiers. Terrain analysis should be a fundamental key skillsfor any soldier, whether they be a rank-and-file grunts or a top-level commander. To neglect sparing a thought for terrain ahead of an upcoming battle is to invite disaster.

Considering that the preeminent threat currently facing Nevaehlen is the Harrower (at least at the time of this essay’s writing), the Valefolk likely can not afford too many such military disasters before their nation simply ceases to exist. The Harrower is a supernatural extra-dimensional entity who commands a legion of dedicants and beasts enthralled by a curse simply called the ‘Mark’. He grows his powers through the spilt blood of the Marked. Should he conquer a city, its inhabitants will, at best, be ritually sacrificed on an altar or forced to help spill more blood for the Harrower until the day they die. The Valefolk face a fight for their nation's very survival; it would be thus be in their best interests to take the threat seriously and weaponise every advantage at their disposal. This should especially include their island’s natural terrain; after all, it is one of the Vale’s strongest defensive assets.

The practicality of terrain analysis and usage still remains even when considering the existence of things that are not bound by the spatial limitations of ordinary human movement. Aevos has no shortage of threats with the capability to casually bypass or outright ignore most unfavourable natural terrain and man-made fortifications. For example: There are many threats that fly, teleport, phase through solid walls. Counted among the Harrower’s dedicants are: soldiers who can ride wall-shattering Northern Mammoths, high-flying Thundermaw Ravens, and highly-mobile Goat Cavalry; his First Zenith, a white-haired woman who can summon a fog of magical darkness and open gateway portals within said fog; and his elite corps of Chosen, each of whom is a mighty spellblade who can teleport between shadows. With such foes at the Harrower’s disposal, it is not completely unreasonable to think at first ‘why bother caring about optimal terrain use when the Harrower has so many things that don’t have to?’

This is because the threat of things that ignore terrain does not preclude the threat of things that do not ignore terrain. For all the Harrower’s powers, the bulk of his legion is composed of more-or-less ordinary human ‘Thralls’ who still need to use their own two feet to move around. When people go off to war against the Harrower, the vast majority of fighting typically comes down to locking swords against the common Thrall.  The Chosen, the Mammoth riders, the Thundermaw Raven riders, the Goat riders, the First Zenith — for all their strengths, they are neither numerous nor powerful enough on their own to destroy the Harrower’s enemies entirely by themselves; their actual tactical purposes all boil down to supporting the ‘main push’ of the Thralls.

The Harrower’s elite forces can also be countered rather straightforwardly, without needing to take too much focus away from preparations against the less extraordinary Thrall. In short: Thundermaw Ravens can be shot down with ballistas and their lightning attacks safely redirected by tall structures and lightning rods. Mammoths are big targets for artillery. Goats ridden as cavalry can not scale steep slopes anywhere near as easily as unencumbered ones can, owing to their riders greatly weighing them down and shifting their weight distributions and centres of gravity significantly further upwards; without the factors that enable mountain goats to traverse mountainous terrain, the Goat Riders would realistically come crashing down the cliffs should they attempt to scale it, so the their movements can be restricted similarly to the legion’s heavy infantry. Furthermore, even the First Zenith and the Chosens’ shadow-based portal and teleportation powers have limitations, and can be countered and mitigated to manageable levels by upgrading Nevaehlen’s lighting infrastructure to be more comprehensive and reliant on magical lighting sources. This will be expanded on in later essays in this series.

While the ‘Shoot the Mage First’ rule obviously still applies, anyone fighting the Harrower must recognise that the common Thrall still remains a main threat on the battlefield; to neglect preparations against the rank-and-file Thrall in order to focus on the Harrower’s more elite, magical, and special forces is sheer folly.

It is perfectly doable to acknowledge and plan around the existence of things that ignore terrain without neglecting to acknowledge and plan around things that do not ignore terrain. Even though there exist dragons that can fly and breathe fire, does that make people who bother adding walls, gates, and towers to their settlements complete morons? It does not. This is because most people still recognise that the threat of ordinary Descendant bandits and armies killing them and razing their homes is still very much a thing. And it is a threat very much worth preparing against, lest their settlements collapse long before a dragon has the chance to.

People still fortify their cities and castles with full awareness that ordinary walls won’t stop every conceivable threat in existence. However, by placing down basic, fundamental defences, they get the security, freedom, and peace of mind to prepare more specific counters to things that can not be stopped by normal fortifications. The same logic applies for using fortifications and natural terrain against the diversity of threats within the Harrower’s legion.

No matter the opponent, any soldier worth their salt should always study the terrain of battlefields, potential and imminent, and think about how the terrain could potentially impact a coming battle. A combination of basic terrain knowledge and a bit of critical thinking can go a long way towards achieving tactical and strategic success.

To pull off the best possible defence of the Vale, each and every defender must at least:

1. Have basic knowledge the lay of the land,
2. Have a decently formed idea of how the natural terrain is incorporated into their defence plans, and
3. Actually physically move to exploit the terrain when the time to fight approaches.

If nobody has the faintest clue where to go and what to do when the enemy comes knocking, they are in for a bad time. It will be even worse if they do actually have all this information floating around in their heads but still end up standing around, twiddling their thumbs, and doing jack-all the whole time as enemies make landfall on the island’s shores, scale its slopes, overrun half the island, and start battering down the city’s walls unopposed. Everyone in the Vale must take action and play at least some kind of active role in the defence of their own community. This fight involves everyone, whether they like it or not. The contents of this essay should help them in that regard.

The main purpose of this essay is to give Nevaehlen’s commanders, Greenblades, and allies a more in-depth and scientific understanding of how to weaponise the Vale’s natural and artificial geography. This will let them hold better-informed and more active defence discussions, which should in turn lead to better tactical and strategic decision-making. It should also help guide the Vale’s architects, engineers, and builders in considering the terrain as they expand their budding civilization beyond the ruins of Talar'nor to other parts of their island. The security the people of the Vale will get from a more optimal and defence-minded approach to construction and terrain usage will pay massive dividends in future prosperity.

Of course, to obtain that security, the Greenblades actually have to physically go and study their nation's terrain with more conscious thought put towards defence. Staring at squiggles of ink on paper is no substitute for real-life experience.

How to study the terrain: A crash course

Terrain analysis can be largely the same as taking a casual stroll and appreciating the scenery. It just involves a bit more critical thinking.

When doing terrain analysis, the first thing to think about is the mission: to what end is all of this effort going to achieve? For example: In the context of the Harrower War, the mission is basically to defend Nevaehlen against a siege by the Harrower’s legion. The success criteria is that Nevaehlen is not destroyed and the Harrower’s troops are forced to leave the island and the Vale alone. The Greenblades can probably achieve this goal by decisively defeating the Harrower’s forces with attrition; if the defenders kill enough of the enemy’s troops, the Harrower may just decide conquering the Vale isn’t worth the cost, back off, and maybe find an easier target to convert into blood sacrifices.

Defenders should try to identify the follow things:

1. Avenues of approach and withdrawal — What routes and methods could attackers possibly take to attack the Vale? Should things go south for the defenders, what routes can they take to retreat back to safety? How will the features of these routes specifically affect the way people move through it?
2. Cover and concealment — What natural and artificial terrain features, magical abilities, or tactics could attackers use to protect themselves from being fired upon by defenders or hide their approach from sentries? Likewise, what can the defenders use to protect themselves from enemy fire or keep their own movements hidden from the attackers’ scouts?
3. Obstacles — What terrain features, natural and artificial, could block, hinder, or funnel the movement of the attackers and defenders?
4. Observation spots and fields of fire — Where are the most convenient spots for the attackers and defenders’ scouts and commanders to observe the course of battle from? What would be the most practical possible spots to observe the important parts of the battlefield from? From which advantageous positions can defenders set up the best possible angles and lines of sight to rain down the most effective possible fire on approaching attackers? From where can the attackers best fire back at the defenders?
5. Key terrain — Which specific areas can the attackers and defenders fight at a considerable advantage over the other? Which areas of the battlefield would be crucial for either side to control in order to assert dominance over the island and achieve military success?

If possible, the best way to go about identifying these things is to personally familiarise oneself with the terrain. A nice, long stroll around the battlefield long before the fight even begins is an effective way to get the above information. For many people, actually seeing things with their own eyes sticks in the mind better than looking at words on paper or lines and colours on a map.

If personally surveying the terrain is not feasible for whatever reason, studying detailed military maps can also work. Such maps show details like grids with XYZ coordinates, accurate terrain contours, and the precise height of the terrain above or below sea level. But on the other hand, these kinds of maps are not very common; Aevos has a dire shortage of the geographers, land surveyors, cartographers, and so on with the needed knowledge, skills, and motivation to produce them. Most maps in circulation are rather stylised and only show a basic overhead view of an area; to use these simpler maps effectively, it must be combined with personal knowledge from surveying the terrain.

Once knowledge of terrain is gathered, that information should be noted down somewhere as soon as possible. It is only natural for people to forget things. It is generally useful to keep a notebook around to write things down or draw quick sketches in. Even obvious or seemingly insignificant observations should be put on paper, for even the little things can end up being significant or useful to remember much later down the line. Doing this allows oneself and the people they are working with to easily and conveniently visualise the terrain in their heads without having to keep walking around the battlefield over and over again every time they forget and want to check back on something. Aside from writing down the information in text, it also helps to draw and annotate maps. These can be shared with others and helps everyone to visualise the information in word-heavy discussions. An example would be Illustration B above, which marks terrain obstacles and various potential avenues of approach. A picture paints a thousand words.

Doing at least some basic terrain analysis should give combatants a good clue on how things will probably go in an upcoming battle. The more potential enemy actions that defenders anticipate and prepare contingencies for, the lower the chance of the defenders getting caught off-guard and forced to fight at a severe disadvantage. The more of a general idea people have of what to do when something happens, the better battles will generally go for them. While it is definitely crucial to be able to think on one’s feet and adapt to a changing battlefield (as no plan ever survives first contact with the enemy), this is no excuse to not bother coming up with any plan at all and simply wing everything. Failure to plan is planning to fail.

Illustration C: Nevaehlen's eastern walls built atop the island’s cliffs. The combination of cliffs and tall, solid walls in close concert makes for an extremely difficult obstacle for attackers to overcome, likely forcing them to seek other ways of breaching the city.

Terrain and construction

Nevaehlen’s fairly spacious, flat, and defensible mountain plateau provides a lot of prime real estate for the civilisation to expand into. But as spacious as it is, none of that space should be wasted. The world can be a violent, brutal, and merciless one at times. Therefore, it would be wise for any new upgrades and expansions to the Vale to be built with the defence of the nation and its people as a high priority. As soon as invaders land on the Vale's shores, houses turn into forts, garden fences become barricades, canals become moats — any and all civilian infrastructure will suddenly become military infrastructure, every aspect of the environment suddenly becomes part of the defence. Failure to plan and build with defence in mind may lead to pain and regret later down the line.

As a general rule: before building a new settlement or fortification, it would be wise to consider the ways in which the locale’s natural terrain can make the task of defending it easier or harder. On a similar note, when planning the layout and placement of streets, alleys, buildings, and decorations within a settlement, it is advisable to think about the ways the specific arrangement of urban terrain being created might affect the course of potential battles that could be fought at the site later down the line.

Even seemingly minor design choices can end up playing a significant role in the defence of the nation. For example: Two opposing rows of connected houses can act as a funnel for enemy troops, making them more vulnerable to traps, artillery fire, and thrown potions. The canopy of an inconveniently placed tree can block line of sight for friendly archers firing down at street-level enemies from a settlement’s walls, towers, and rooftops. A settlement’s curtain wall built too close to a large rock or the branches of a large tree on the outside could be easy for enemies to parkour over. A curtain wall placed too far away from a nearby cliff might buy time until coastal erosion drags it into the sea, but this would come at the cost of opening up more viable space for enemies to set up raid ladders; this would force defenders to further spread themselves out to protect these still-vulnerable walls from infiltrators, thereby negating the defensive advantage of building by the cliffs in the first place. Because almost any aspect of the environment can end up acting as part of the Vale’s defensive infrastructure, construction going forward must be built with more practical consideration to defence.

If engineers can incorporate advantageous terrain features into a defence, they can end up with very strong fortifications while saving a lot of time, effort, and resources. It would be much cheaper and easier to build a strong defensive position using what is already provided by Mother Nature than if they were to try and accomplish the exact same thing while also doing extra terraforming, building everything from scratch, and compensating for a location’s inherent weaknesses.

For a case in point: The former Principality of Talar’nor, whose territory the Vale of Nevaehlen inherited, is a textbook examples of people seamlessly incorporating advantageous natural terrain into their nation’s defence. The Talar’nori picked a very defensible spot to build their main city. It sprawls across the northeastern half of the island with over three-quarters of its perimeter naturally protected from direct assault by tall, steep, and rocky cliffs. The city’s northern, eastern, and southeastern walls (except in one certain area) complement the natural defences by keeping out mountain climbers and parkour artists. All this makes the city a rather tough nut to crack, even in its ruined state.

The result of this rather clever defence-minded approach to city building is that it leaves an invading army only a few vaguely viable avenues of approach with which to invade the Vale. This includes the narrow and crumbling old Talar’nori bridge on the east side of the city. It also includes two narrow slopes on the north and south sides of the island, which are only marginally less steep and hazardous than their adjacent cliffs. All of these approaches make for advantageous key terrain for the Vale’s defenders, and can be blocked off rather easily. The bridge can be blown to deny the enemy an easy river crossing or stepping stone for teleport jumps. And the slopes can be made even more hellish to scale by strategically placed forts, fortified settlements, or field fortifications.

It should also be noted that defensibility does not have to be mutually exclusive with aesthetics either. It is perfectly possible to build a place that both looks good and is practical to defend. While making actually defensible architecture would require a bit more thought than usual, the Vale’s people will surely appreciate the increased security and safety. It also saves on time and effort compensating for weak defences at the last minute when invaders actually come knocking. It is typically better to do things right the first arounds rather than try to fix things later.

A useful thought exercise for anyone defending anywhere is to put themselves in the shoes of an attacker and challenge themselves to think up ways to conquer the location themselves. If defenders walk around imagining themself as the one actually having to besiege or assault the place, it makes it a lot of easier to identify what weaknesses the enemy can potentially take advantage of for an easier win; what obstacles might make it less easy to win the fight; and brainstorming how they would exploit these weaknesses, overcome these obstacles, and achieve victory in the easiest and most efficient way possible.

With all these considerations in mind, defenders can then think more effectively about how to address weaknesses in their defences and better deal with potential enemy approaches. If the mind still comes up blank for ideas, it is worth visiting a library and studying the past. There is a whole world of revelation to be seized just from reading up on historical battles and commanders. Alternatively, one can also consult the experience and wisdom of people in other nations who have been in a similar boat. When it comes to warfare, no one should care about plagiarism if it helps them win.

The Vale’s natural terrain is a massive force multiplier: if properly utilised, it would effectively grant the island’s defenders the combat effectiveness of a force much larger than their actual size. Well-thought-out fortifications are another big force multiplier, which grant the defenders the ability to take on much larger forces with significantly less difficulty compared to fighting a pitched battle on a field. Smartly combining advantageous natural terrain with decent fortifications would allow the Vale’s defenders to fend off invading forces many times larger than their own. Adopting a more tactical and strategic mindset towards the expansion of the Vale will, over time, result in a much safer, more secure, and more prosperous nation.

 

 

Illustrations D and E: A 1-metre-thin section of curtain wall on the south side of the city. It is likely that enemies will immediately identify it as a weakness and topple it with a trebuchet, thus opening up what most would think to be an easy path directly into the heart of the city. This can be either a good or a bad thing depending on how the Vale’s defenders prepare for the scenario.

On intentional ‘weak points’

There is a (rather concerningly) common military and architectural philosophy in Aevos that people should intentionally leave big, glaring weaknesses in their defences ‘tO mAkE tHiNgS mOrE fUn’, ‘bEcAuSe iT iS mOrE aEsThEtIc’, or 'iT wOuLd mAkE fOr A bEtTer sToRy'. If anyone were to seriously and unironically suggest such an idea in the middle of a planning session, immediately kill that person on the spot before they can contribute another word to the discussion. This will, in most cases, be doing the entire defence a big favour; such people end up helping no one but the enemy.

 

It should always be assumed the opposing team will actively do their best to win. One should never plan a defence as if the enemy will hold back for childish and silly reasons like fun and fairness. Not every potential opponent out there is so honourable and chivalrous. When most people identify a weakness in any fight, it stands to reason that they will try to exploit the hell out of it. To fail to take potential enemies seriously is to invite disaster the moment a smart, cunning, and unchivalrous opponent comes along and takes advantage of this mindset.

A settlement is a huge investment for everyone involved in its founding and expansion. It is where they live, work, and relax. It would be a painful waste to establish a settlement, nurture its growth, and see it rise to prosperity, only for someone of reasonable intelligence to come along and destroy it with minimal effort, all because someone's dumb opinion was not ignored. Losing something one has a significant stake in seldom ever ends up being fun anyway.

However, there are times it is tactically advantageous for defenders to not build fortifications to be too strong or optimal. While these may seem like weak links in an otherwise strong defence, they are in fact bait meant to entice the enemy into acting in a predictable manner that can be planned around or lure the enemy into a trap. This approach can often prove more effective than chasing the fantasy of a truly invincible fortification. To quote a certain famous Li-Ren general: 'All warfare is based on deception'.

Competent attackers will generally try to make the best possible moves to achieve victory without wasting too much manpower and resources. For example: if they can bloodlessly starve a fort’s defenders into submission without worrying about time or an enemy relief force, they likely will not bother losing massive amounts of troops and equipment by launching an assault on the fort. If they do need to assault a fort, they may try to undermine the walls or concentrate artillery fire to create a wide breach for troops to flood through rather than scaling the walls a few men at a time with ladders and siege towers. If they do need to scale the walls, they will try to avoid more strongly defended wall sections in favour of weaker ones. For an attacker to fight less than optimally when doing something as difficult and costly as assaulting a competently defended fortification will only incur great losses.

It is also worth noting that, no matter how strongly one may build a fortification, someone will always eventually think up a creative and unexpected way to overcome or bypass the obstacle. For example: the Harrower’s First Zenith is likely Aevos’ foremost expert at thinking with (shadow) portals and can probably find or create an obscure gap to exploit in even the most thorough of magical lighting infrastructure. Likewise, the Chosen can probably find similar opportunities to infiltrate the Vale and sabotage the defence from the inside. Another potential bypass they may likely try to exploit is through the sewer or cavern networks beneath the Vale. Other enemies besides the Harrower can probably think of countless other ways to pierce the Vale if given enough time. It is simply impossible for the human mind to conceive of every possible idea to conquer a place and put into practice a fool-proof way to totally invalidate it. One should never underestimate human creativity and ingenuity.

This is why dangling seemingly easy and straightforward options in front of attackers’ faces often turns out rather effective. Attackers will generally try not to make life any harder for themselves than necessary. Most commanders would rather do what is easy, obvious, tried, and tested than hurt their brains or waste time brainstorming elaborate and unconventional schemes. This is typical human psychology, and it can be observed throughout the rest of Descendantkind as well.

Of course, this bait is not guaranteed to work on everyone. A novice enemy commander may rush headfirst into a trap, hook, line, and sinker. But a wiser, more well-studied, and overall more competent commander would probably be fully aware of this tactic and hold back their forces until they think of a better approach.

In any case, the wise commander does not seek to create insurmountable obstacles, but dilemmas. If attackers face only obstacles that each seem too difficult to tackle head-on, they will simply hold back until they eventually think of an unexpected and creative solution. Defenders should instead want the attacker to act suboptimally and make mistakes. This can be achieved by just crossing out most of the enemy’s ‘easy’ options and leaving as remainder the ones where the defenders can most readily turn the tables on the attackers. Attackers should ideally be incentivised to act in predictable ways the defenders have already prepared contingencies for. This is not necessarily saying that trying to create a good all-around defence is folly. All parts of a defence should be fairly solid. The point is that defenders should never permit a weakness in a defence without first crafting a solid and cunning plan to punish the enemy for moving to exploit it.

Illustration F: The Northern Slope from the top. It is perhaps the steepest and most perilous of the two slopes permitting entry to the Nevaehlen plateau from the shoreline.

 

Illustration G: The Southern Slope from near the shoreline. There is a fairly defensible ridgeline at the top of the slope, though a curve on the slope blocks line of sight between the shore and ridge. Further development at and around the slope will be needed to make it harder for invaders to conquer.

Conclusion

The Valefolk have much to gain and little to lose by adopting a more tactical mindset towards the development of their civilisation. Though the Greenblades are capable fighters who have done well to maintain the Vale’s freedom and independence thus far, the defences they inherited from the Talar’nori and Mother Nature will be nowhere near enough to weather a serious assault by the armies of the Harrower or larger Descendant realms – or at least not in their current state. The people of the Vale must take immediate action to improve on their homeland’s defences before the enemy makes their move. To this end, it would greatly benefit them to take another, more critical look at their island's terrain and seriously review the state of their defences. It would also greatly benefit them to do so with firmer understandings of terrain analysis and terrain exploitation in mind. If they instead just leave things till last and haphazardly panic-improvise field defences just as an invasion force is about to make landfall, they will most likely end up losing the war. Wisely thought-out preparation will be key to victory.

The Vale of Nevaehlen has the potential to grow into a veritable fortress-nation, one of the most fearsome strongholds in the entire continent, even. Surrounded on all sides by towering cliffs and deep water, the Vale has the natural geography to make it happen without too much cost or effort. All it would take is for the Valefolk to achieve this is to the initiative and make more active and optimal use of their home field advantage going forward. The Vale’s natural terrain is its strongest defensive asset. To not properly expoloit it may as well be shooting themselves in the foot.
