photorealistic image of a dungeon hall that is is 20 feet wide and 90 feet long, the walls plastered taupe and painted with murals of demons, human sacrifice, devilish revelry, monsters destroying and devouring humans, and people being ravaged by the power of wind, whirlpools, blazing flames, and landslides. At the end of the hall, in front of two large wooden doors, four symbols are placed in mosaic in the floor: a silvery white circle, a brown triangle, an amber-red diamond, and a blue-green square. --ar 16:9
