The following account was recorded in the agent's log during your transmission: A sprawling, ornate grotto unfolds beneath a crystal-clear lake's surface, sunlight filtering down through the water in shimmering curtains. The air inside is stale and damp, but somehow I can smell the scent of smoldering incense wafting from ancient, corroded braziers, even though they're submerged in water. Umm, the grotto's walls are adorned with strange, glyph-covered frescoes depicting creatures like, from ancient Sumerian mythology, and water currents somehow form miniature whirlpools around the symbols, as if being drawn into them. Shimmering iridescent feathers are stuck to the stone ceiling, and they're... flapping gently, like they're still attached to something.
