"Now, this world is extremely small. You could easily orbit it on foot in under five hours."
-The Landlord

Xineerauqs is the name of the planet The Landlord created, and subsequently built Domus Facina on. It is a small planet about 10 miles in diameter. This planet also seems to be the only planet in its galaxy, but it still has clouds, a sun, stars, and a moon.

Other than Domus Facina, the planet has been revealed to have multiple facilities littering it, all of which are run and maintained by The Contractor. These facilities include:

It should be noted that Cosmos and Mid will not be part of the Domus Facina cast, nor do they actually have anything to do with the facilities named after them.
