Jenny Storm left ten years ago. Apparently she won a hand of blackjack against the captain and he let her go. [Not mentioned: how she brought him the soul of every other passenger to be even allowed to play, and how she used those souls to power he galleon.] She came back to find her brothers, but...

[A shrug. That didn't work.]

She learned some of the captain's magic here. With blood and sigils. I can show you the symbols, if you want.

[Maybe the weird skeleton man can make some sense of the weird runic bullshit?]
