The following account was recorded in the agent's log during your transmission: Water's pouring down a massive, ancient stairway like a waterfall, cascading into a seemingly endless pit. The air's thick with humidity, and a faint scent of frankincense wafts up from the depths below. Umm, the walls are covered in what looks like Enochian script, etched into the stone like it's some sort of map. A shard of the Black Sun appears to be wedged into the stone steps, radiating an otherworldly chill despite the sweltering heat.
