The following account was recorded in the agent's log during your transmission: Water's dripping down these massive, moss-covered stalactites in a massive underground cave. Umm, the air's pretty humid, and the smell's all damp earth and... something metallic, like copper or something. This old, rusty locomotive is somehow wedged sideways in a wall, like it just phased in there from somewhere else – part of it is sticking out into the air, and the other part is just embedded in the solid rock, no signs of any excavation or anything. The sunlight from a distant cave entrance is casting this really warm glow on everything.
