Base

A base is a large piece of architecture that serves as a link between Sburb players and their Exiles. They arrive on the players' original homeplanet on the very Meteors that force them to enter Incipisphere in the first place. The bases hold several Sburb related gadgets such as Appearifiers and Homestuck Interface Devices.
