Shoot!! You really should have thought to bring a disguise. You're soooo not allowed in the Dreaming Spire. But it might be okay, because everyone's going the opposite direction. The klaxon telling people to take shelter in the undercity is still going strong, so everyone's headed toward the nearest subway stations. A few people try to stop you, but you stammer some kind of excuse about forgetting something at home, and soon there's no-one on the streets. You hope your guardian is okay. You haven't seen him since you left for the library, but since he already knew all this was going to happen he might have just gone underground ahead of the crowds.
