Origin
Alastor was once a human living in medieval Italy. He was in love with Chalkis. Although she was in love with him too, she rejected his advances. Spying on her, he discovered that Chalkis was regularly molested by her father and brother. Having discovered her secret, he devised a plan with her to take revenge on her family. He killed her brother and she fed him to her father, who choked when he discovered he had been eating his son.
