One of the Jurrugar, who are the most elite of the Guruk Gorefiends. They possess recollection and a bit of magic power, because they have been granted the boon of mucor. As a mucor-enhanced Guruk, Mgrauleshk was sent to open the portal to Dereth by the Burun Kings to round up Morgluuk and Torgluuk. Kukuur Reeshan would then enter the new portal and find the way to bring the other Kukuur Masters to the world of the Fiazhat Gods. There the Burun would complete their destinies and become the rulers of both their own world and the world of these would-be usurpers. He was captured by the Burun Ruuk forces of Morgluuk and swore allegiance. With the death of Morgluuk and the disappearance of Torgluuk, Mgrauleshk took over the leadership of the Burun forces.
