You enter a large green room.
The Floor eminates a sort of, temporal energy you find similar to ones in your kitchen and other parts of your house. A kind of energy you get when you spend the night in bed with insomnia, waiting for something you know happens to happen, but it just quite doesn't happen. Luckily for you, all your friends are probably awake at that time along with you too, it still feels eerie.
You also notice on some of the floor the same kind of floral design displayed at the top of the mausoleum entrance and the rest of sburb-related technology.
If you were a sleuth quite like your friend Meowrage, you would start putting together a few pieces about this place being absolutely related to sburb, but, you aren't, so you just settle for it being somewhat related to sburb.
