The following account was recorded in the agent's log during your transmission: Umm, a kilometer-long freight train is somehow stuck to the ceiling of a vast, cavernous space filled with the stench of rot and smoke. Its cars are covered in rust, acid scars, and bioluminescent mushrooms that etch Ethereum transaction hashes into the metal in real-time... the air is thick with the smell of smoke and ozone, and it feels like it's about to rain inside this place. Shredded squid entrails are dangling from the train's undercarriage like macabre icicles. The ceiling - or what would be the floor, I guess - is slick with oil and engine grease.
