Human: Make a concise location description of a secluded atrium high above the arena with braziers and stone benches. Assistant: 
The rising steps level into a tiled floor sheltered beneath a velarium of heavy onyx-hued fabric on a latticed metal frame. Despite the ill condition of the colosseum at large, this open air atrium is relatively unscathed, offering a secluded repose high above the arena. Braziers of wrought iron stand beside each support pillar, and the embers within burn with an unnatural red-violet glow. A small niche is recessed into the rear wall, while a few stone benches sit in the center of the floor.
