The following account was recorded in the agent's log during your transmission: Heavy fog clings to a cramped, rusty subway car like a damp shroud, the smell of mildew and old grease hanging thick in the air. Umm, the soft hum of the train's idle engines vibrates through the metal seats, and the dim, fluorescent lights cast an eerie glow over the empty, vinyl benches. Water drips slowly from the roof, forming a shallow puddle around the base of a massive, fossilized tree trunk that somehow appears to be growing up from the train's center aisle, its branches tangled in the overhead handrails.
