Gerion Mutt

According to Ranulph's Account of the Sack of Hogstone:

'Gerion Mutt was the fourth bastard son of Valon Mutt. A noted warrior who served aboard the Mutt flagship, the Hound's Tooth. He was killed in 419 during the Sack of Hogstone, by one of the Guardians of Hogstone. His body was taken back to Mutt's Crag aboard the Hound's Tooth where Valon Mutt was said to have mourned over him for half a year.'

Under interrogation from Ronan and Gauner, Ben Greyship, grandson of Mutt ally Gordyn Greyship, told them that he had heard rumours that Valon had made a deal with someone or something, and that Gerion had been brought back to life, that some had said he was exactly as he had been before, while others said he seemed different now.
