Wernher was once a high ranking member of the raider class in Pittsburgh in the late 2200's. He participated openly in the hegymony that had been established by the charismatic leader of the raiders, Ishmael Ashur, but was dissatisfied with his status as an underling. After he staged a coup and failed, Wernher was enslaved and forced to work with the people he once oppressed while performing his duties as a raider. Dissatisfied with his new, more subserviant position, Wernher escaped his bonds by deactivating his explosive slave collar, and went into hiding. Wernher used his status as a freed slave to manipulate other slaves into rallying behind him as a force for change. Wernher knew about a cure which was being for the terrible disease that afflicted many Pitt slaves, and promised to conduct the research himself, and make it available to all Pitt slaves, as well as freeing all Pitt slaves from their oppressed status.
Wernhern manages to make contact with the player by way of hijacking a radio signal and broadcasting an open cry for help. He explains the dire conditions for workers in the Pitt, and the need for someone to help him overthrow the brutal regime. He convinces the player to infiltrate the Pitt disguised as a slave, and work their way to meeting the Pitt's overlord Ashur by performing tasks in the Pitt and winning a gladiator style tournament.
After winning the tournament, the player is instructed by Wernher's inside contacts to kidnap Ashur's daughter, the infant Marie, who is the key to curing the deadly degenerative mutation which has effected large segments of the Pitt's slave population. She is the only known living person with an immunity to the mutation. He also requests that the player assassinate Ashur and his guards, though it is not required.
If the player successfully kidnaps Marie and delivers her to Wernher's assistant Midea in the Pitt, Wernher shows no gratitude, nor does he appear to take any action towards freeing the slaves. It is discovered that Wernher's intentions had never been nobel, and that he simply planned to replace Ashur as the new overlord of the manufacturing industry that the Pitt hosted. The player has the option to kill Wernher in retribution.
