Calvert Mansion

The Calvert Mansion is a location in Point Lookout which will be added to Fallout 3 in the Point Lookout add-on.

It is inhabited by a single ghoul called Desmond and is constantly being assaulted by tribals. According to Tobar, the building holds hidden treasure.

The Mansion is the 1st of the two main buildings in Point Lookout, !SPOILER! Near the end of the The Local Flavor/A Meeting of the Minds quest thread the mansion is destroyed when Calvert attacks Desmond using tribals forcing him use the failsafe blowing it up, also you can be harmed in the blast if you go too close to the mansion as it is destroyed, the angered Desmond fuelled by the death of his "Pups" charges into the lighthouse (filled with robo-brains and turrets) and faces the brain of Calvert giving you the choice of sides, Calvert or Desmond. If you choose Desmond you get the key to the reward vault inside the lab and all Desmond asks is to leave him to his research. If you side with Calvert he will try to kill you with his army of robots. Killing him ends the fight early.
