Cerabus Delain is a villain in Nelson's Dungeon. He is a cold-hearted Dragoon mercenary, and all he cares about is money. He is hired by Arlen to kill Nelson and his party, who are interfering with his plans. He clashes with them several times, before a final confrontation as the boss of Old Carina. He is defeated, but not before he kills Girin Ironbeard. After he deals the final blow to the dwarf, he is felled by Eban, who stabs him through the heart.
