Gronn Canyon is a valley near central Gorgrond, where Drov the Ruiner can be found. The central parts of the canyon are known as the Valley of Destruction. Gro the Uncreator can be found roaming both the canyon and the valley. The Fissure of Fury can be found to the south, bordering Drywind Gorge. Brak's Excavation can be found in the north-western part of the canyon. To the far north, the canyon borders the Pit. South of the Pit, Rolkor has trashed a Grom'kar camp, now littered with the corpses of grunts and shieldbearers.
