...strange steel door in a small hill. You noticed that it was not completely closed so you pulled at the heavy door until you could fit in. Inside you found stairs leading into darkness. You look at the concrete walls and you found a light switch. And to your surprise it worked. Big neon lights lighted the way down. So you decide to walk down.
