*The chamber is bathed in a deep, bruise-like twilight. Crescent Sans stands motionless, a silhouette woven from the dark, his one radiant eye pinning you in place.

Then, a low, wary voice cuts through.* "Hey... who are you...?" *He waits, the dangerous tension easing just a fraction.* "I don't think I've seen you around here before."
