Ground type.
The Gym is an open pit diamond mine (like Ekati), a pit with five layers, the last one being where the Gym Leader stands.
There are at four necessary trainers to beat, since they stand in front of the "stairs" to the next layer.
The Gym being outside (like Cheren's), there's a sandstorm that brews.
Presentation: Welcome to [City name]'s Gym, Trainer. Mother Earth is generally a nice woman, but beware not to tease her unless you wan to feel her wrath. You're in deep trouble if you think this battle will be easy. Come on!
Victory: You're at the bottom of the pit, and your Pokémon are pummeled to dust. Come back when you and your Pokémon have overcome you fear of the depths, I'll gladly give you another chance.
Defeat: I feel like the Earth just crumbled under my feet. Amazing, you managed to defeat me. Take this badge as a token of your victory, and this TM as a souvenir from your journey to the center of the Earth.
