Compound

The compound is an unmarked location in the Commonwealth. It lies on the west shore of Mystic Lake, across from Covenant.

Background
The compound was created by Dr. Roslyn Chambers, an anti-synth fanatic. Its purpose is to fight the Institute by rooting out suspected synths and abducting, interrogating and torturing them, and eventually killing and dissecting the synths for scientific purposes. It is responsible for the project to turn Covenant into a refuge for the victims of synths, which aids the compound by administering the SAFE test to those passing through. However, Dr. Chambers admits that the test is not completely accurate and that some of those captured and tortured turn out to be human.

Layout
The sewer is a small subterranean section accessible through a door inside a big pipe. The pipe is based partially underwater in Mystic Lake, to the west of Covenant. A fisherman mills around on the pier above the entrance, complaining to anyone who approaches that they are scaring away the fish he is trying to catch. Two skeletons are found sitting above the entrance, surrounded by home comforts such as a TV, furniture, and decorations.

Inside the pipes, the location is fortified by the compound guards. The last chamber features a chemistry station, an armor workbench and a terminal. Adjacent to the chamber are three prison cells, one of which contains Amelia Stockton. The chamber is used as a torture chamber by Dr. Chambers. If she is killed, the whole base, and Covenant, will be hostile towards the Sole Survivor.
