D. Allen

Sergeant Dennis Allen was a Brotherhood of Steel member, one of the members of Roger Maxson's original team.

In 2134, a faction led by Allen gained strength, and they urged the Elders to let them explore the southeast ruins of West Tek, called the Glow after being hit by a nuclear bomb, for artifacts. The Elders refused, so Allen and his divisionist group split away from the Brotherhood of Steel, taking some technology and weapons with them. Other members of the team included Soto, Jensen and Camarillo.

They made it to West Tek Research Facility after 20 days. The radiation levels began to shoot up as soon as they could see the giant crater. They concluded that their armor and anti-rad supplies they'd be fine for a least a day of exploringand that the technology they had the potential of recovering was worth it.

They climbed down the crater to the first level and as there wasn't much of value on this level, they pushed on. Unfortunately for them, the security sensors had been burned out on the first two levels, but not on the third. Jensen killed before he knew what had happened. Allen tried to regroup, but only Soto and Camarillo made it back up here to the first level with him. All three of them eventually died because of power armor failure. Before he died, Allen logged what happened to the expedition into a holodisk which was later found by the Vault Dweller.
