Desmond Lockheart

 is a non-player character who will be added to Fallout 3 with the release of the Point Lookout add-on.

Desmond is a ghoul that before the Great War used to be a secret agent. Now he lives in the Calvert Mansion. His home is constantly being attacked by a tribal cult that want to gain some secrets hidden within its walls, but, from the looks of the trailers, Desmond's fortified the Calvert Mansion quite well with ceilng-mounted turrets and guard dogs.

As seen in demos, once you enter Calvert Mansion you are greeted with quite the firefight and Desmond gladly recruits you to help fend off the tribals. After Desmond "recruits" you, he retreats, probably off to his survielance room. Leaving you to pick up the pieces, and ward off the tribals from the decaying ruin known as Calvert Mansion.

During the Point Lookout trailer, he is briefly shown (about 18 seconds in) wearing Dirty Pre-War Businesswear and wielding a Combat Shotgun. Then later in the trailer he is shown wielding a Sniper Rifle and fighting off what appears to be the tribals of Point Lookout.
