New Legacy of Armada

Well I'm open to fill any sort of plot ideas, and I've always liked how proud the Armadas are. I'd love for him to learn about them and grow up with the same amount of pride, and perhaps instead of it being sibling it could be someone unrelated. I really just want a reason for him to keep his guard up, but if breaking familial bonds isn't something you want I can swear oath to the armadas no problem, so to speak. ;)
