Urlakk Urruk was an Ork warboss who fought against the Imperium during the Great Crusade in the late 30th Millennium. He was originally one of the warbosses subordinate to the Warlord Urlakk Urg who ruled the great Ork empire centred on Ullanor Prime in the Segmentum Solar.
After the forces of the Space Marine Legions under the command of Horus Lupercal shattered Urg's forces during the Ullanor Crusade in 000.M30, Urruk fled with his Greenskins to the Chondax System. There he established his own Ork empire which he ruled as its titular "overlord" until it was destroyed by the White Scars Legion during the Chondax Campaign at the time of the outbreak of the Horus Heresy between 000.M30 and 007.M31.
