Swamped

You've seen just about everything you can make sense of in here. You might as well see if they'll intervene if you go anywhere else.

You step out another doorway and see... well, nothing. Or rather, a completely empty room. No furniture, nothing on the walls, no people. The only thing you can see is a series of squares marked on the floor. There's a small red one, surrounded by a slightly larger green one, and the pattern continues for a while. All different colors. Aside from that, the room is just a very dull shade of white.

You're just about to leave when a muscular person walks in, carrying a large scroll. He stares at you for a moment, walks around you, and steps in the middle of the smallest square.

Then he just stands there, as if he's expecting something to happen.

Now what?
