The Airship Everbright, Skypirate Flagship.

What do you do when your livelyhood is shot out from under you in the same attack that flattens your hometown and erases everyone you care about from existance? If you're a proper gentlemanly ship's master, you gather some drinking buddies, raid a military base, steal the airship that did it, and start your war for revenge under the Jolly Roger.
