After talking to everyone in the lobby and realizing the unconscious ones wouldn’t wake up anytime soon, I wandered out into the surrounding hallway.
The curvature of the building was even more obvious here– the hallway was almost definitely a circle. If so, it probably didn’t matter which way I chose to turn… I heard voices coming from the right, though, so to the right I went.
It didn’t take too long to find the other students, and… I recognized one of them?? I thought that voice sounded familiar!
