[He wonders now, after what the Merchant said.]

When I arrived, we were all kept on a ship and they had a mirror. A cursed mirror. And they'd put us in front of it and it would borrow things from us. Memories. Abilities. the mirror was broken when we were freed from the ship but... the Merchant said its curse was transferred to the body in the lake.

It takes pain and bad memories away from you.... but only a little. Not completely, they come back after a while.
