Ulsquire Shauncy is an afflicted resident of Mort'ton and a local priest and teacher in the town which was famed for its religious ceremonies. Ulsquire is located in one of the three still-standing houses of Mort'ton, along with a sink acting as the town's only water source. He is good friends with Razmire Keelgan, the local shop owner.
He features in the Shades of Mort'ton quest and must be cured multiple times of the affliction, originally by the Serum 207, a temporary cure, and then eventually permanently with the Serum 208 once the player has enough knowledge to make it. In the quest, Ulsquire is the one who tells the player about burning shade remains and gives them the knowledge to complete the quest and access to the Shade Catacombs and the Shades of Mort'ton minigame.
