Canterbury Commons has become a constant battleground for two costumed "super humans" -- the sinister AntAgonizer and misguided Mechanist.”— Fallout 3 loading screen
Canterbury Commons is a trading post and a small town located on the eastern edge of the Capital Wasteland, which in the year 2277, is currently suffering from a full blown battle between two "super humans". It is inhabited by five wastelanders and can be found north of Washington, D.C., north of Vault 108, and southeast of the Temple of the Union.
Canterbury Commons is the end of the Capital Wasteland's established merchant caravan route.”— Fallout 3 loading screen
The settlement is built into what appears to be the remains of a small pre-War town, with the current inhabitants only using a small part of the buildings available. The town's only permanent merchant, Joe Porter, lives in an old Dot's Diner. Adjacent to this building is an old garage which is home to Dominic and Machete, and across the street is the old fire station, now Uncle Roe's house which Roe shares with his nephew Derek Pacion. Behind the old garage, a small brahmin stable can be found.
In front of the town to the west is a large circular cul-de-sac where caravan merchants appear regularly.
- Grognak the Barbarian - carried by Derek Pacion, needs to be pickpocketed.
- Dean's Electronics - inside Dominic and Machete's garage on a desk in the room to the right as you walk in.
- Highwayman's Friend - unique tire iron, inside Dominic and Machete's garage, on a shelf right next to the Dean's Electronics book.
- Moira Brown grew up in Canterbury Commons.
- The caravan merchants inventory may be upgraded by speaking to Uncle Roe in the unmarked quest Merchant Empire.
- If the player kills or disables (with the Robotics Expert perk) the Mechanist's robots before they can leave for the robot repair center and disappear, they will respawn after 72 hours at the location of their corpse and remain there permanently. They will level with the player, and will change into higher-leveled robots when the player reaches the appropriate levels. For example, a robobrain and a Mister Gutsy will be replaced with sentry bots once the player is at level 20 or above. The robots are friendly towards the player and the town citizens, and will attack any random wasteland creatures that may approach the town.
- Killing either the Mechanist or the AntAgonizer before they fight will cause Uncle Roe to give you 400 caps but will not allow you to start The Superhuman Gambit quest.
- Sergeant RL-3 resides here if dismissed after becoming a companion.
- The player character may take up residence in the town (see Dominic and Machete's house).
- The player character loses Karma for killing members of the town.
Canterbury Commons appears only in Fallout 3.
