The following account was recorded in the agent's log during your transmission: Crystalline stalactites hang from the vaulted ceiling of a damp, abandoned subway tunnel, refracting faint, flicker-free fluorescent light into tiny rainbows across the grimy, concrete platform. Like, a low hum is vibrating through the still, stale air, which is heavy with the smell of damp earth and mildew. Water's pooling on the platform, somehow flowing upwards to merge with a vast, crystalline lattice structure that's filling the tunnel, its facets reflecting the fluorescent light into an endless, fractal pattern. Uh, a train's somehow running along the crystal lattice, its carriages disappearing into the tunnel's darkness.
