When you first enter the gym the only light comes from the door when it opens, the moment it closes it's pitch black. Once the door closes though torches light up the wall enough to see the entire gym, except the actual floor which is below the islands. From the entrance platform (which is suspended 3 feet above the padded ground) there is a bridge leading to two other small isles. Each isle rises in height:entrance 3 feet, 2nd isle 4 feet, 3rd isle 6 feet above the ground. At the third isle there is a lift that takes the trainer up to the battle field. They all lead to the battle field which is suspended 12 feet above the ground.
