Backrooms secret hideout

An idea I've had for a while now. What if someone actually turned the Backrooms into a secret hideout and safehouse? So I've gone ahead and done it.

Shadow Company have converted the backrooms into a secret out of the way safehouse and secret cache.

With a large stash of Element 115, a huge arsenal of weapons and ammo, a large supply of Nova 6, gold, top secret files and various other supplies. It's the perfect hiding place, and no one knows how to get to it except for Shadow.
