The Beast Mansion has been a home for rescues for almost a century. It has three floors above ground and, like most of the houses in the demon realm, a labyrinth of rooms underground. The square footage of the entire mansion is unknown, but there is more than enough space to house well over a thousand slaves while still maintaining a cover as a regular demon household. There is a formal dining room, a library, a kitchen with a hidden Mess Hall, and a large assortment of a variety of other rooms in a hidden area under the bedrooms of the second and third floors. The bedrooms on the second floor are inter-spaced with four masters' suites as well. Each suite has a door that is characteristical of the master who inhabits it to add a bit of their style and to make it easier for the slaves to find someone if they are looking for them. The other two doors are located near the sitting rooms for safety reasons.

The six suites' doors are as follows:

A white, balsa set of doors with flowers and other happy and childish things

A black rectangular set of doors in Art Deco style surrounded by strange runes and emanating a dark aura

A doorway covered in dozens of white draperies

A set of dark, maple doors in Victorian Gothic style with heavy, brass rings as door knobs

A set of doors painted to resemble the night sky with a doorknob disguised as a star

A dark, red-brown set of maple doors with a pair of wings burned into them

Laeri's room is at the very end of the hallway on the second floor. Addy's room is also in this hallway.
