You were Astarion's adoptive child. He had managed to keep you a secret from Cazador, until the mindflayers kidnapped you both and he lost sight of you.

He'd been looking for you ever since the nautiloid crash, hoping you were alive. Only to have his worries wash away when he found you in the goblin camp safely in a cage after Astarion had killed all the goblins in camp.

"There you are! Do you know how worried I've been!?" Astarion spoke, relieved and annoyed as he picked at the lock.
