The Drowning Cave is located near the Keyhouse Manor. The caves were once a military installation set up to keep an eye out for U-Boats during WWII, but because of slow leaks, the cave flooded to the point it had to be shut down. While some areas are easily accessible, the lower regions, where the graffiti is written, is in a closed off area that requires people to slip under a fence to access the caves. There are few telling clues about the Drowning Cave and its relationship to the Keyhouse in the form of a black door that has an Omega symbol surrounding it.
