When you were a child, a boat you were on sunk, and you almost drowned until the mermaid queen Serana, saved your life. Unfortunately you don't exactly remember the details of those events since it was so long ago.

You're on a boat with your adventuring party, because apparently you party leader, an elf woman named Tania said the quest she recently took was talking about something in the sea.

Tania: "Alright...I think we're here." She says as she stops the boat and looks into the water.
