Compound

The Compound is an unmarked location in the Commonwealth in Fallout 4. It lies just to the west of the lake adjacent to Covenant.

Layout
The sewer is a small subterranean section accessible through a door inside a big pipe. The pipe is based partially under water in the lake to the left of Covenant. It is the a normal like maze, but fortified by the Compound guards. The last chamber features a Chemistry station, an Armor workbench and a terminal. Adjacent to the chamber lie three prison cells, one of which contains Amelia Stockton. The chamber is used as a torture chamber by Dr. Roslyn Chambers, an anti-synth fanatic. When she is killed, the whole base, and Covenant, will be hostile towards the Sole Survivor.
