Kas frowned in thought for a moment, watching the confusion taking place then reached up toward on of the glowing rocks and concentrated. Taking carefuly aim, he pointed his finger at the backside of one of the imps then formed the image of flame. The imp's tail suddenly caught fire and it leaped into the air with a yell, then dashed around the room screeching at the top of it's voice. The flames engulfed it quickly and it shrieked then turned into a pile of ash. Kas stood up and looked around the room, then pointed at another of the imps.
It paused and looked at him then vanished. The remaining imps followed it's example rapidly, vanishing as quickly as they had come.
