Before the events of the films, Davy Jones, a human, fell in love with the sea goddess Calypso. She gave him the task of guiding the spirits of the dead lost at sea to the next world. Jones was granted immortality on the condition that he could return to shore once every ten years. However, when Jones returned to shore after ten years of service, Calypso failed to appear. Feeling betrayed, Davy Jones made a secret agreement with the Pirate Lords, which resulted in Calypso being bound into a human body. She took the name Tia Dalma and began to practice Voodoo and Obeah magic.
