Clamors have a playful kind of intelligence, and they appear to desire communication. Being able to mimic any sound they have ever encountered, clamors wander the Material Plane emitting a nonsensical cacophony of voices, crashes, clicks, roars, and music. Since they are usually invisible, most adventurers that encounter a clamor walk away from the creature without ever having realized that they had met one. Many a sentry on duty has heard only his own voice in response to what he thought was someone walking around out in the darkness; what he really heard was a clamor trying to talk to him.
