Thin Shaun is a Barrow Keeper in Ireland. He offers the blood of animals to the spirits that made the barrow, appeasing them to keep the refuge's magic strong. He is the father of Konal, and in Rage of the Fallen it was mentioned that he is not long for the world, as Keepers only have one child and then die. Thin Shaun tricked Tom into going into going into his and Scarabek's cottage so that Konal could use Tom to feed.
Thin Shaun is described as sickly looking, with a bald head and thin limbs.
