Because I am kind and merciful and would never do anything bad to you, I will be allowing everyone to later "request" roommates, though obviously the Arbiters and Aberrations can't request each other unless they're special cases and are in the same building.

So go ahead and start thinking about who, if anyone, your character might want to request later, though both parties have to agree before a switch/room relocation can occur.
