The paper read:
Dear people I really hate,
I would have met you all in person, but, you know, I hate you. Anyway, I suppose it's only polite of me to tell you all that this was another trap. This building, and much of the surrounding city, will soon be...gone. Just like you! So...good luck with that.
Love,
Joe
OOC: And now I have to go. No groups, just get out of the city. When everyone is out, que EARTH SHATTERING KABOOM (warning: kaboom may or may not be earth shattering. In fact, it most certainly won't be). Good luck! Oh, and feel free to imgine all kinds of hell breaking lose as you are making your way out of the city (explosion, gunfire, regular fire, the works).
