Thanatos Barca was one of the higher elven lords in Illunii, the former head of the House of Barca. He was the husband of Nyx Barca and father of Persephone Barca. When his daughter went missing, he grew increasingly worried and eventually contacted some heroes of the Grand Alliance to bring his daughter back. He perished in Illunii, doublecrossed by none other than Persephone who had only been using him for her own ends.
