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 giving them the knowledge to complete the quest and access to the Shade Catacombs and Temple Repair. He does not have any particular use after the quest, but may still be spoken to by players.
