((Vote 1/2 you're halfway to being accepted. As I said in an earlier post, big things are still being changed within the guild so what I am about to say may be not necessarily true in a week. Anyway, at the moment the guild is divided into three sections, warriors, rangers and merchants with the current aim within the leadership being to come up with new sections and hierarchies. With someone like you, who may not excel at the sword or bow, you could still join the rangers or the warriors but the amount of training you would have to do would be pretty horrendous.
To outline the three sections, warriors are the driving force of the guild, earning money through escorts and raids, they will also have a sub-section of guards who will be charged with the defense of the castle.
The rangers perform the more subterfuge based jobs, scouting jobs and provide a supporting role in battles in the form of archery and traps. Assassinations, counter intelligence and intelligence are just a few of the things that a skilled ranger would do that are wildly different from warriors.
The merchants are effectively the economic side of things in the guild, without them the guild would fall apart. Hence, nearly everybody to do with the facilities, feeding and other non-combat things would be classed as a 'merchant'. With your said aptitude for writing, I would consider putting you in charge of the guild library as one of your jobs (we cannot give each merchant one job for the moment, what with a lack of numbers). Merchants are vital to the guild and make a lot of money along the way, making them some of the most powerful members of the guild and granting them the ability to join the council through pure influence over other members. Your redstone skills could be put to great use in the construction of the castle as we are thinking of deforesting the local area around the castle and just filling it with traps, leaving a single path to the gates, where a drawbridge could completely deny enemies access. If this doesnt seem like the right path for you, i'm sure I could find you a place in the military side of things.))
