Chantico
From PotC Wiki
Chantico is the Aztec goddess of fire. She is also the patron of Isla Esquelética. She manifests herself in the form of a fire that never goes out, a flaming human form, and a volcano. The Aztec feed Chantico by trapping prisoners in her volcano until they die.
When Jack Sparrow and Fitzwilliam P. Dalton III visited Isla Esquelética in the past, they were captured and sacrificed to Chantico. With the help of the Timekeeper, they were able to escape.
She then actually appears to Jack and Fitzwilliam and tasks them to fix the warping of time that has occured on the island, giving them 12 hours to complete the task or be destroyed. With the help of Tia Dalma, they undo the damage the Timekeeper caused by giving the Timekeeper to Stone-Eyed Sam and then separating it from him upon the last few seconds of the time limit, causing him to revert to a corpse and restore the timeline. Chantico appears again to congratulate them and speaks with Tia Dalma of how she may eventually be freed.
