Opal Pokemon Gym

The Opal Gym is built into the side of a mountain; half of it is in the mountain, and half of it is out. The half that is out is made out of concrete and looks like a normal building. The half of it that is in the mountain is completely covered with ice. There are stalactites formed from ice hanging from the ceiling, and enormous stalacmites rising up from the ground. The ground and walls are solid ice, except for a cave that's in the back wall on the Leader's side. It's above ground level, a small cliff leading out from it then slanting down onto the ground. The Gym Leader's side of the battlefield is covered in ice as well.There's a pool in the middle of the field, and that one part of the Gym Leader's side happens to be not frozen. The Leader is Kyarameru Higashi Li, and she uses Ice type Pokemon.
