Chana is a mythical creature. The siren. But unlike how the myths present sirens she is the opposite. Or at least she tries to be.

One fateful day you walked along the beach silently. In the distance there is a lump or rock of some kind. Laying on the beach. You approached it and found that it was a siren. You help her into the water again. You thought nothing of this interaction afterwards until you found yourself confronting the siren. ”I have come to repay you.”
