Dralnu

Dralnu, Lich Lord was an undead necromancer from Urborg who aided the Coalition forces before betraying them. He bore a remarkable resemblance to the Metathran commander Thaddeus.

In life, Dralnu had been a warrior, but he fell in battle and was reanimated by an unknown Urborg necromancer. However, Dralnu retained an unusual level of awareness and intelligence as a zombie and therefore became the apprentice of the lich lady that had reanimated him. Dralnu learned the necromantic arts from the lich lady and used them to enhance his body and mind to become a lich, then he killed her and took control of her undead legions. He also took control of her underground city of the dead called Vhelnish, which he converted into a working city rather than a place for the lich lady to display her undead collection. From there, Dralnu became a major unseen power in Urborg, commanding thousands of undead minions.

During the Phyrexian Invasion Dralnu allied with the Metathran forces on Urborg and helped them advance towards the Stronghold. Later on he infected Agnate with a plague in order to take control of the Metathran army. Commander Grizzlegom realized this and revealed Dralnu's betrayal to the Metathran generals. Dralnu feigned innocence and in turn accused Grizzlegom of killing Agnate (which was technically true.) In order to resolve the matter Dralnu and Grizzlegom agreed to submit themselves to the Metathran commanders by binding their arms behind their backs and wearing hoods whilst the Metathran passed judgement. Dralnu was deemed guilty of the murder and was executed.
