The following account was recorded in the agent's log during your transmission: Massive, crystalline pillars support a vaulted ceiling in a sprawling underground cathedral, while pale, silvery light filtering through the walls casts a kaleidoscope of reflections off the intricately faceted columns. Like, the air's heavy with the scent of old stone, and I can see dust motes hanging perfectly still, as if time itself is paused around them. Uh, the silence is absolute, broken only by a low, creaking groan that seems to be coming from the earth itself... and a massive, solid stone door at the far end of the cathedral is slowly opening by itself, into solid rock.
