A knight who used to govern a peaceful town before the Gracian War, today it is called the Ruins of Agony. Called Sir Grindel in his lifetime, he was captured and brutally tortured to death after losing a battle against the Gracian Army. Underlings of Beleth hiding in the town stole his body and resurrected him, making his soul corrupted. Having lost his knightly honor and sense of self-sacrifice, now he has turned into a devil and tries to spread his pain to all he encounters in his endless wanders through the Ruins of Agony.
