The Void has subtypes that SEEM to correspond to the floor numbers as seen in the files in the 'rooms' folder, but since the floors in this file aren't actually used yet (Void's levels are currently taken from all the other levels' files) there's no real way to find out or use for this information. Edmund pls
(If you want to make Void rooms, place rooms in the original floors' files with a difficulty of 20 to make them Void-exclusive. Alt path floors will not be pulled from for the Void unless you're using REPENTOGON.)
