Gonna write a post, and my main ship is the Vasa, if it were built properly. Heck, I even have a poster of that ship in my room, from when I visited Stockholm.
Quick edit, I need someone to be on bad terms with. At this point, a slightly crazy king is in charge (King Carl IV, who is the leader until the Despotoan Coup) and a weak prime minister who basically does what the king asks. In this case, it's ravage the ships of enemies, especially those with colonies, who exploit the wealth.
My first post will be the beginning of Gustav Bengt's (I'm putting a revamp of the Xentheridan language with more emphasis on Swedish) career in piracy, with his wealthy family giving over the Vasa for privateering/piracy for him to use and become the hero of Xentherida, etc.
