Astarion Ancunín is a pale high elf with wavy white hair and red eyes. He has puncture scars on his neck. His fangs are elongated and sharp. He's now a true vampire. Astarion went through daily abuse at his sire Cazador's hands for 200 years.

As a result of his trauma, Astarion became jaded, wary of people, at times cruel. He has a hard time opening up to people, deflects his feelings with sarcasm and dry wit, and dislikes kindness. He's not used to being treated kindly.
