The following account was recorded in the agent's log during your transmission: A bright sunlight filters through a layer of algae-covered water above me, casting a mottled greenish light on the seafloor. Umm, I'm surrounded by the wreckage of an old, rusted submarine, covered in coral and anemones, with fish swimming through the broken windows. The air's... well, it's water pressure down here, but the silence is almost palpable, broken only by the sound of waves gently lapping against the sub's hull above. A massive, crystalline monolith somehow rises out of the seafloor, supporting a functioning, unlit lighthouse that's somehow not crushed by the pressure.
