fronting headspace
active mates and host reside here.
essentially a small room. there are four walls, although only three of which are visible. the far wall has a door leading out into the labyrinth. the right wall has a door leading to the holding headspace. both doors are impossible to look through, there's just black. there is a couch on the center right of the room. there is a giant "locker" by the left wall, essentially an iron maiden.
holding headspace
less active mates typically reside here.
we know that the room is a much larger room than the fronting headspace, but unaware what it looks like otherwise. it's a place for burned out headmates to relax and rebuild their strength.
the void/labyrinth
unwanted mates and "guards" reside here.
essentially a giant, dark maze that goes around both rooms of the headspace. only internal affairs type headmates know how to navigate it. any mates who risk causing damage to either the host's body or mind are brought out here and imprisoned in a hellish section. we don't know where it is.
