Klasha Ursova

Klasha is the pirate captain of the Rustbucket, a massive mess of ships smashed together to make a goblin's paradise at sea. She was dumped usurped by her boyfriend first mate, and made a deal with a deep-sea goddess that Klasha would serve her in exchange for the ability to survive. She was picked up a week or so later by her current traveling party, and they're closing in on her old ship.
