The following account was recorded in the agent's log during your transmission: Dark, granite cliffs tower above a vast, crystalline cave system, umm, sunlight filtering through the transparent walls in a warm, golden hue, like, midday sun. The air is crisp and dry, carrying the faint scent of minerals and damp earth, and the silence is only broken by the gentle dripping of water somewhere deep within the caves. A World War II-era submarine somehow rests intact, undamaged, and still fully operational, nestled in the crystal formations, despite being hundreds of feet below the surface and with no apparent means of accessing this cavernous space. The propellers slowly rotate, sending faint ripples through the motionless air.
