Sonitus nodded, and held out his hand outstretched. He proceeded to create a bible of trapped sound, not letting any escape. Inside this bubble, there would be an odd whooshing sound, similar to when a car drove by. There would also be a slight breeze. Outside, no sound could be heard from the circle, even if the prisoner screamed as loud as possible, it still wouldn't make it through ((In Sonitus's bubble, no one can hear you scream)).
