The following account was recorded in the agent's log during your transmission: Dark, iridescent mist is swirling inside a massive, hollowed-out cathedral, casting a shimmering pattern of colors on the stone floor. Umm, the air's got this heavy, incense scent and it's pretty still, with the faint humming noise echoing off the cathedral's walls. The cathedral's interior is somehow shifting according to the Poincaré disk model, with arches and pillars melting into each other like wax. Shards of stained glass are embedded in the walls, depicting cryptic symbols from the Cygnus X-1 map, and the air seems to be vibrating at an almost imperceptible frequency.
