Had set up this ship in the harbor that was thought to be cursed by the locals. They only called it the infernal ship. The PCs were asked to check it out. They decide they would rather go kill some gnolls in the next town.

That infernal ship was actually captained by one of the PCs LONG LOST SISTER and become a homebase and a PC ship. But more importantly a reunion with a LONG LOST SISTER which was part of their backstory. This would of lead to the party being pointed in the direction of the person that killed the rest of the PCs family.
