The following account was recorded in the agent's log during your transmission: Water pours in through the damaged hull of a World War II-era German U-boat somehow stuck vertically in a mountain meadow, a bright rainbow forming in the spray above the conning tower. Seagulls are just pecking at these rusted pipes jutting out of the hull, while... uh, a massive, slow-moving tortoise somehow pulls a whole array of ancient, dusty-looking VLF receivers on a wooden sled up the mountain. The air's thick with the smell of diesel fuel and grass. The sound of distant howling echoes through the clear, still air, and it's like late afternoon, with the sun shining down from low on the horizon.
