This is a battle arena located inside a vast manganese crystal cavern. Tall pink rhodochrosite columns stand like ancient trees, with black pyrolusite streaks crisscrossing the rock walls. Delicate purple manganite chandeliers hang from the ceiling, and the entire cavern is bathed in soft pink and purple glow emitted by the crystals themselves. The ground is paved with gravel and ore, with mining cart tracks stretching into the distance, and rusted mining equipment including ore carts, jackhammers, and lanterns scattered around. A clear underground lake in the middle of the cavern perfectly reflects the crystal structure of the ceiling. In the very center, a huge intergrown rhodochrosite formation called Manganese Heart glows intensely. Crystal dust occasionally falls from the top of the cave, and the space is filled with the crisp sound of dripping water and unique acoustic echoes, presenting an otherworldly aesthetic of mineral beauty.
