After making it through Victory Road, you will come upon a large opening in the side of a mountain. This opening leads to a couple of doors. You walk through these doors, and inside you find a large room with a healing station, a shop, and a few people dotted here and there. There are a few more doors that you can walk through if you want. These ones have you enter an elevator, which brings you up to the first member of the Elite Four. As you beat each member, you travel up another elevator to the next one. This is a hard and difficult challenge that not many have overcome.
