Wernher

 is an escaped slave from The Pitt who requests assistance from the Lone Wanderer in helping with a slave rebellion. He explains that the Pitt's Raider leader Ishmael Ashur developed a cure for the horrible mutations afflicting those living in the city, and wants the Lone Wanderer to help him and the slave rebel leader Midea retrieve the valuable commodity.

Wernher's true intentions are largely up to the player's interpretation. It is subsequently revealed that that Wernher was Ashur's lieutenant before he was enslaved for betraying his leader. According to Sandra, Wernher once attempted to steal Marie, which may have been the reason for his enslavement.

If you object to Werhner's plan to kidnap Marie in order to obtain the Cure and free the slaves, he will tell you that sometimes changing the world involves getting your hands dirty.

If you side with Ashur and successfully manage to get Wernher to leave he will curse everyone and everything, including Ashur, the Pitt, the raiders, and the slaves. This could be taken to suggest that his motives may not have been all that noble.

Characteristics
Wernher levels with the player, and his health and skills are on the exact same scale as the game's NPC Companions, making him noticeably tougher than most other human NPCs short of Commander Jabsco or General Jingwei. Amusingly, this makes him noticeably tougher to kill than his rival, Lord Ashur, who despite having significantly stronger-than-normal armor has only about as much health as a standard Brotherhood of Steel Paladin or (at higher levels) Enclave Tesla Soldier.

Because Wernher levels with the player, his performance in the DLC's opening firefights against Pitt Raiders varies significantly based on the player's level. On low levels he can be overwhelmed and beaten by them, while on high levels he should be able to wipe them out singlehandedly without the player's assistance.

He fights with a Scoped .44 Magnum, and wears a Merc Cruiser Outfit. However, his equipment is in below-average condition.

Equipment
Items found on Wernher:
 * .44 Round, Magnum (12)
 * Abraxo Cleaner
 * Frag Grenade
 * Power Plant Key

Bugs

 * There is a bug where Wernher, after killing all the raiders in the first battle upon entering the Pitt map, will discharge a few clips of his magnum into one of the trains. He will sometimes eventually stop.
 * There is a bug in which Wernher's left eye is fluorescent yellow. This is sparked from approaching him from different angles. It's just a minor glitch that doesn't seem to resolve itself.
 * There is a bug where after killing all of the raiders Wernher will start walking across the bridge and get himself killed if the mines aren't disabled.

Appearances
Wernher appears in The Pitt DLC pack for Fallout 3.
