Greetings Archduke Ostromir, You begin your writing with arguments that attack the man, not his opinions. The House of Barbov has never claimed to be a fully Raev house, this assumption is false. Rather, they are mixed with the blood of Old Hanseti in the land of Athera, Carnatians in Vailor and other houses that are not strictly Raev. Barbanov has, many times, been a faithful supporter of an Empire of Humans, as their lineage descends from Alexander I, Holy Orenian Emperor. Your line, however, descends from bastards of bastards of bastards, many of which are notorious bandits and traitors. Could Marius really be surprised when you turned your cloak as well? You go on for paragraphs of the crimes of Horen, while this is good, it's entirely irrelevant as Marius is a Barbanov, not a Horen. It was not his administration that boiled and betrayed Andrik, Sergei Kovachev and Demetrius var Ruthern are dead, and he was merely an infant when the Deep Cold Rising occurred. It failed for a number of reasons, it's reasons for rebellion were questionable at best, and Andrik failed to wait and garner the necessary support to hold the passes into the North, or to even have a unified rebellion. When you say he was a "True Raevir King" and that you would've follow him, I only think that you would've followed him simple for his betrayal of his Oath, though due to your lineage I am not entirely surprised.
Your, and many others, specifically the Dwed's, paranoia about some feigned Hansetian Imperialists is laughable at best. Haense only controlled the land that it had controlled for decades in this realm. May I remind you of the similarities that Courland and the Empire hold in terms of land? The only former Imperial lands that are free of Courlandic control are that of Mardon, the unstable Westerlands, and the former puppet Kingdom of Lorraine. The man claims to be a King because he is still afforded that title, as per the current Peace Agreement. Tobias the Scaled only claims them because of a rumor.
You talk of the "Adrian Legacy", which is utterly hypocrisy. I'd argue that he supported the Adrian Legacy by supporting the Crown against Ashford insurgents. Furthermore, did not the ancestors of Tobias, Percival, fight against Adria in support of his Ashford liege? Your own people endure hardship because you cannot make up your mind about which side to support, and you and your ancestors are fond of changing your banners at a passing rumor.
You are the Archduke of Hanseti-Ruska in name only. A stolen title for a thief, fitting I'd say. Your support died amongst Haense peasants when you turned your cloak. Nobody wants to follow you, you are merely a puppet and dog of Tobias. You have no support, no men to guard your title, the only thing that protects you is your knees hitting the floor in front of Tobias and the act that follows. The Houses under you do not supply you with bodies either, as the lands are granted to incompetent fools who can only manage to twiddle their thumbs while their homes fall into decay. Only your ancestors led the Raev to ruin, and I expect you to do the same.
Sariant Philipp of Metterden.
