The following account was recorded in the agent's log during your transmission: Uh, thick rivulets of what appears to be pure darkness are oozing from gashes in the belly of a gutted, cathedral-sized beached shark. The carcass is surrounded by scattered, mangled fragments of ancient shipwrecks and twisted metal debris. Air pressure's incredibly low here, making my ears ache, and the silence is almost deafening – I can feel the stillness, like a physical presence. The sky above is a deep, sickly green, and it's getting darker by the minute, despite what should be midday.
