The cages

All buildings have a number of;cages; to save the old stuff, or things that do not want in your room (or bags, or furniture in the room you do not use). There is no predefined cage per room, unless there is a hallway with many cages. If you see an empty and unlocked, it's yours. Put a lock and you're done.

Look carefuly, because maybe some other past owner's of your room have left things and has put a paper with the number of the room. The cages can be either above the buildings, or in some bunkers out there.

The bunkers are under some doors leading stairs to descend. Seem bunkers of the second world war (actually, we doubt that they are, because it has doors of containment and that sort of thing). The truth is that there is very scary and I do not like being alone there for a long time! hahahaha
