When joining the thieves, anyone was forced to pick a new name for themselves, forsaking their prior identity. Whilst this might have been a challenge to some, it was not for Morgeth. In an attempt to cast away the horrors of the past, she adopted the new psuoedonym. In the gutters of Orgrimmar, Taint was born. The thieves did not shun the young orc for being a warlock, and in a way Morgeth's new name let her embrace her curse and her taint. It was pity, and perhaps a misplaced sense of kinship, that made the acting enforcer of the thieves take notice of her. Calling himself Crude, the older orc took Morgeth under his wing and attempted to teach her the more subtle ways of survival. The relationship eventually took a romantic turn, but was conflicted from the very start. Crude took pride in planning ahead, whilst Morgeth could not break the habit of living on a day to day basis.
Whilst Morgeth may have been a grand survivor, Taint was a useless thief. At this level of thievery, one had to do more than rely on speed and a lithe body. A favourite method of the Sixty was to gang up upon unknowing travelers in the Drag, as was the case the day they encountered an orc warrior by the name of Gnash. Caught by the warrior's blade, Morgeth was nearly disembowelled. She was not alone in frequently getting hurt, however, as most of the gang were somehow prone to get into trouble. Crude's sinister plots caught up with him, and in a fit of desperation, he faked his own murder. This event left Morgeth in turmoil, believing herself to have failed protecting the one person who had ever made any attempt at taking care of her. Numbing the pain of such a loss, the young orc found solace in the friendship in a pair of new thieves, being the male orcs calling themselves Trill and Gash.
The three would spend a lot of time together, and whilst their thieving conquests were more successful than usual, it would eventually have to come to an end. It was during an act of revenge against the orc Gnash, who's actions still were fresh in the memories of most thieves, that both Trill and Gash were nearly killed by the warrior and his friend Greggar Ironfoot. Morgeth tried to aid in tending the two back to health, but the event left Gash blind and in time he left the thieves, never being able to surpass his handicap. Trill and Morgeth, however, grew closer. When Crude eventually revealed himself to be alive, Morgeth grew furious, and thought herself betrayed. Her descent into madness was perfected by her attempting to murder Crude, which promptly ended their relationship, and left her open to Trill's advances.
Beginning to think of the thieves as a family of sort, Morgeth became plagued with the inadequacy of her powers. Wishing to protect those around her, she began to delve deeper into the teachings of the Cleft. She was encouraged by Trill, who claimed that he would need protection. But to embrace the fel proved dangerous, because with every sliver of power gained, Morgeth's sanity seemed to wane. She began to bleed profoundly from her nose and mouth, and her nights were consumed by nightmares. Eventually she did not sleep at all.
