The following account was recorded in the agent's log during your transmission: Air's thick and damp, like, there's this smell of mildew and rust wafting from the countless, intricately carved copper pipes snaking across the walls of this vast, abandoned aqueduct. Water trickles through the pipes, casting an eerie, whispery echo that's amplified by the structure's acoustics. A sliver of sunlight filters in, illuminating the faintly glowing, bioluminescent moss coating the walls - and, uh, the air itself appears to be imperceptibly rippling, like a stone cast into a still pond, around an unblinking, perfectly spherical void that's just hovering there, somehow unremarkably.
