[So we're definitely keeping with the all concrete theme in the room the door reveals, but—it's only about the size of a small bedroom, if that, and...almost cozy looking? There's a bookshelf in one corner, and some seating spaces (beanbags stolen from the library, chairs stolen from the cafeteria) gathered around a card table in the middle of the room with a couple of books and stray papers on it. Less cozily, there are a few weapons leaning against the walls; things you'd find in the weapon closet, but without any of the glitter.]
