Vorsh

Vorsh was a bald troll belonging to Gree's tribe. He helped capture Vereesa Windrunner and Falstad Dragonreaver, but died in a battle against hill dwarves — the rescuers of Vereesa and Falstad.

Speculation
While the trolls speak about having worked with the Horde, the type of troll that they are is never specified. While it would be common to assume that they were forest trolls, given the time period and Vereesa's mention of the Troll Wars upon seeing them, Jon-Jon Jellyneck and his tribe are local jungle trolls to the area who also work with the Horde during the Cataclysm; meaning that they may have been part of this tribe.
