Porenut

Porenut is one of the Ancient Elders serving Diadora. He has a body of stone, and is immune to most forms of attacks. Due to his invulnerability, he's haughty and proud, and maddens easily when insulted. He's quite fearful of death.

He was assigned by Diadora to assist Fenrir, and blocked way between the Second Exhibition Hall and the room where Fenrir waited in the Art Gallery, using space-warping sorcery to enclose the door in his body such that if he dies, the door would never be able to be opened. The price he paid for such sorcery was the summoning of the Fairy Ring, which became the key for the door. Astaroth used the Fiary Ring to open the door, resulting in his death.
