Grel Trumgol is a swamp on the northern side of lake Ilfanarg. It is a hot, humid and bug-infested area. It is a haven for numerous bullywug tribes, black dragons, trolls, and very aggressive and large alligators. In the northeastern area of this wetland are the ruins of Grul Vund.
During the First Epoch, this area was heavily fought over by the Tulukhan and the dragon-blood hordes of Thashangriel. As a result, the restless spirits of many of these creatures still wander the swamp as ghosts or undead. These spirits will usually fight their ancient enemies over other creatures.
