The following account was recorded in the agent's log during your transmission: Echo, sunlight's peeking through a stained-glass mural covering the ceiling of a grand, ornate subway station filled with iridescent tiles that seem to be reflecting more colors than the visible spectrum should allow. Like, the air's got a weird, almost-neutral scent, not really smelling of anything, while the ground's got a slight vibration from trains that seem to be moving without making any sound. Umm, somehow, trains are seamlessly passing through each other as if they're not really occupying the same space, Echo, but that's not really what's caught my attention – there's this odd, hieroglyphic graffiti etched into the walls that seems to be... breathing?
