Porewit is one of the three Ancient Elders serving Deirdre. He has a very long chin and a bit of beard, and wields a tin staff in his right hand. Much of his body, except his head and arms, are inside a painting. When his mouth is closed, his chin might be mistakened for his chest. He attacks with light bullets from his right hand, as well as vines summoned from his left hand. He is capable of gather energy from the painting he's in to heal himself, making him invulnerable while the painting is intact.
He was assigned by Deirdre to assist Fenir, and blocked a hole between the First and Second Exhibition Halls of the Art Gallery, where he was slain by Shura. Before his death, he revealed that he had lived a longer life than Shura's, and that he was glad to finally be able to rest, ending his tiredsome existence.
