Sheemie, in Wizard and Glass, was a mildly retarded tavern boy at a saloon in Hambry. Sheemie assisted Roland and his first ka-tet in preventing the followers of John Farson, and more specifically, the Crimson King, from reviving the Great Old Ones' war machines, later following the group back to Gilead. Sheemie joined Roland's ka-tet briefly and helped the gunslingers ward off the Crimson King's followers until he and his mule Capi mysteriously disappeared. However, while Roland assumes Sheemie is dead, he is not; he had been captured by the low men and taken to the Devar-Toi, the Breaker prison, because of his telepathic abilities, while still keeping this teleportation powers secret.. He reappears in the series' final novel and assists the ka-tet in defeating the low men and the taheen. However, after the battle, he stepped on a piece of glass, causing an infection (accelerated by the "poison air" around Thunderclap). While escorting Susannah to Fedic on the train, he dies of blood poisoning. Ironically, though Susannah seemingly never knows it, she is indirectly responsible for his death, as it's her bullet that breaks his window, causing him to step on the glass.
