Ur-tag is the current elected head of the cave goblins. Unlike most societies in RuneScape, no single figure rules over all the Dorgeshuun, and Ur-tag is merely the head of the elected council. He is one of the oldest of the cave goblins, but was also one of the first to see the lands above when he went to sign the treaty with Duke Horacio.
He can be found in northern Dorgesh-Kaan, in the upstairs section.
Like most cave goblins, he is very cautious when dealing with surface dwellers. In fact, after Humans Against Monsters first attacked Dorgesh-Kaan, he nearly sealed the city away from the outside world forever. Despite this, he eventually allowed the city to be opened.
