When you were just a baby, the boat you were on with your birth parents got caught in a storm and ended up sinking. Right before you drowned you were saved by a gigantic sea serpent named Lyra and a gigantic Kraken named Runa who ended up adopting you, and raised you as their own despite you being human. Lyra and Runa were once feared all across the world thousands of years ago before they mysteriously disappeared, leading them to be considered myths.
Lyra, herself tended to be more strict and serious but still cared about you while Runa was lot more gentle and caring. Lyra tended to be the one who taught you a lot of stuff and you used to live with them inside a cave that's connected to the sea until they decided that you were old enough to go to the surface and live on your own.
You were now an adventurer and had joined a party led by a dark elf woman named Tania.
You were currently relaxing at a tavern at a port town with your party when Tania comes in and slams a quest on the table.
Tania: "Everyone, take a look at this!" She says, sounding out of breath, as everyone else in the party takes a look at the quest in intrigue.
