(I'm thinking that Tia Dalma might've been some sort of goddess or something? I've read a lot of rumors.. some people on IMDB have said that she needs, like a bunch of certain pirate together all at once to set her free or something.

The Turkish soldiers picked it up and fought over it, but then, the Kraken put a quick end to it. The Kraken spit it up at the end, right before it swallows Jack. (and I could kill Elizabeth for chaining him to the mast.)
Question: who rescued Elizabeth from prison in DMC?
