Tholl the Toll Troll, a rather large troll, was colleague to a toll gnome. He was not very bright, but was quite vicious, especially with his axe. He would be summoned if there were any problems at the toll gate, including those who tried to climb over the gate or REZROV it.

At the beginning of the tenth century, the troll and gnome operated an Eastlands toll booth in the Cavern of Doom. Sometime prior to 957 GUE, the duo crossed the Flathead Ocean and ran a Westlands toll booth on the GUH-2 running between Bozbarland and the Glass Maze.
