The 5th planet branching off of Undercroft as a painting-portal comes Endomet. Perhaps the “mechanical innards” of the Rockerverse. It’s a very “BackRooms” Level 2 vibes-planet. Hallways and corridors are lined with machinery. The only danger Fox has found so far are literally steamy hallways too hot to pass through and some black mold. I like to think it is SOMEWHAT occupied, like maybe little Klink-Klank people.
