Tull is a town located south of Princetown and north of the Mohaine Desert. The town consists of a boarded up grocery, a livery, a tailor, a church, a barber, a dry goods emporium, and a bar. In the 2003 revised version ofThe Gunslinger it is also revealed Tull contains a train yard.
Roland comes to Tull in The Gunslinger in search of the Man in Black. When Roland first arrives in Tull he does not receive a friendly welcome. He goes into the local bar, Sheb's, and meets Alice. Alice eventually persuades him into sex. While in Tull, Roland goes to the local church and meets Sylvia Pittston, the local preacher. Roland goes to Sylvia's home one day and learns she is carrying a child given to her by the man in black. Roland uses his guns to kill the unborn child, provoking Sylvia's wrath.
The entire town of Tull meets its end when Sylvia Pittston convinces the town to kill Roland, who decided to make a very unpleasant attitude: Roland alone murdered all the people in Tull. He was very sorrowful after it was done, but then he thought it was needed because he have to go to the Dark Tower, so he couldn't die in that city.
