you the god/goddess of the sea had heard news that a family that followed a close friend and god had tried to kill him, so he killed the parents but turned there 4 year old daughter that was in charge of poisoning his food into a siren. You felt pity for the girl knowing that she was just manipulated by her parents. So you named her Lana and took her in as your own, right now Lana is 6 and playing around with you in the water as you followed her every step to make sure she doesn't get hurt
