At the beginning of the voyage, Kraseawei will have told captain's youngest daughter while they're all having supper that her ship sank one night, and she spent several days clinging onto some railing until she was rescued by none other than Alda the Cruel and the Bloody Sword. 

"I must have looked like a drowned rat when they hauled me outta that water. But Alda looked me up and down, then decided, 'Alright Kraseawei, I could use a cabin girl, we'll try it if you like. I'll most likely kill you in the morning.'"

"She told me that for three years! 'Good night Kraseawei, good work! Sleep well, I'll most likely kill you in the morning,'" she said, shaking her head in disbelief. 

"Didn't you try to escape?" the daughter asked.

"Oh, aye, that I did, took a boat and started rowing, but I didn't get far, caught by another pirate captain, 'Hideous' Mitrik. He brought me back to her, and his mate Captain 'One Legged' Theodore, so they could have a proper pirate captain tribunal and see what devilish thing she'd do to me. So there I was, before the mast, the crew at me back, and the three most horrible captains I'd ever laid eyes on, and Hideous spat on the deck and said, 'guilty.' One Legged nodded his head, and said 'guilty', so I knew I was a goner. But Alda shook her head and said, 'That there is the best cabin girl I ever had,' and stood up pointing these loaded crossbows at Hideous and One Leg's heads, and she said, 'And I'm prepared to send you to the... blazes,' iffen you don't change yer vote."

"And they did," she sighs, shaking her head. "And after those two acquitted me and slunk off the Bloody Sword, Captain Alda looks me in the eye, all angry-like, and me life passed before me eyes. But she said, 'Get to work. I'll most likely kill you in the morning.'"

"Then last week, Alda summons me to the quarterdeck, and tells me and the whole crew my debt to her was square, and she set me ashore, and that's how come I'm on this boat with you."

It will be said with sincerity, except maybe when she calls the three pirate captains the most horrible ones she's met. If anyone takes her aside to ask why her ship sunk, she'll shake her head. "I told them I saw another ship, running without lights out there, and they didn't believe me. It came up and rammed us amidships, tearing us in half. I'm luck to be alive, I am."
