The following account was recorded in the agent's log during your transmission: Water's pooling on the worn, travertine floor of an ancient, domed Mithraeum, reflecting the fading sunlight filtering through a small oculus above, like, casting an intricate pattern across the stone. The air's heavy with the smell of damp earth and aged stone, and it's eerily still. Uh, a massive, crystalline bull somehow is embedded in the center of the altar, its facets slowly rotating as if driven by an unseen mechanism, while the surrounding torches seem to be burning with a smokeless, colorless flame that's not consuming any fuel. A low hum is vibrating through the air, syncing with the crystal's rotation.
