(Tapping on the name of each room pops up a little blurb at the bottom of the screen. It seems, from the general tone of the descriptions, that MONO-9000 wrote these.)

Lobby – Here’s where you kids will meet up when I’ve got important announcements to make! Sometimes its hard to convey the… tone unless you’re here in person. The drama. The mortal terror. Y’know what I mean?

Dorms – Look, i put everyone’s names on their rooms! And their pictures on the doors! I bet even the green-haired dumbass could figure out which room is his!

(These descriptions are… not very helpful. Seems like I’ll need to explore the new areas for myself to learn anything worthwhile…)
