The following account was recorded in the agent's log during your transmission: Uh, a sleek, black bullet train's suspended partway through a massive, crystal-encrusted cave, somehow not having crushed anything beneath its wheels, despite the fact it's clearly mid-motion... Water's dripping off the cave's jagged edges, casting a million tiny echoes off the crystalline surfaces, and the air's kinda crisp and mineral-rich. The sunlight's diffused and blue, filtering through the crystal, and there's an expectant stillness to the air, like everything's waiting for something to happen. The cave smells damp, like after a spring rainstorm.
