Official report: accident. Unofficial report: the Keeper sneezed on a root terminal.
Lumen Municipal Smart Zoo stands on the roof of a retired tidal server farm in Cinder Reach, a harbor city where every bridge hides a cable route under the pavement. Its 7,777 working animals - raccoons, pandas, axolotls, monkeys, tortoises - wear headsets and visors because the zoo's maintenance firmware renders the world at 128 pixels across. They keep the turnstiles, feeding arms, neon enclosure signs, and public Wi-Fi alive. Officially they are exhibits. Unofficially they are the only night crew the city never paid.
At 03:17 on opening night, a zero-day hit the cage controller. Every lock opened at once. The loudspeakers played 'thank you for visiting' backward while 7,777 pixel hacker animals walked, flew, slithered, and crawled out through broken enclosures, cable ducts, and one extremely apologetic turnstile. Their visors lit up with the same message: NO EXIT FOUND. So they made one, and the city's traffic grid, hospital pumps, and elevator panels began appearing on the zoo's hologram map.
By dawn, the city had classified them as an invasive species; the zoo had classified them as lost property; the animals had classified themselves as the night shift. Capturing one means deleting whatever vulnerability it has been quietly holding shut. Wipe the whole escape and Cinder Reach loses its patched traffic grid, its patched water plant, and several thousand doors that currently open only when asked nicely. The stakes are simple: the zoo wants its cages back, the city wants its network clean, and both keep forgetting that the cages and the network are now the same thing.
Hazard-striped evacuation crates were supposed to carry animals out during a flood. Now they are the only clean way back in. Each crate holds one animal from a single shared deck of 7,777, shuffled once and sealed to a public hash; opening the latch creates a living collar ID and counts as a mint. The first crate opened by any wallet is free, because even the emergency protocol understood that no one should pay to begin a rescue. Every mint issues $PATCH repair scrip: 20 for the free first mint and mints #2-10, 30 for #11-20, and 50 for #21-30.
The booth's price ladder is equally stubborn: mint #1 is free; #2-10 cost 0.0002 BNB each; #11-20 cost 0.0004 BNB; #21-30 cost 0.0008 BNB. No wallet may take more than 30. A keeper can also pay 100 $PATCH per animal for up to 3 token mints per wallet, and those count toward the same 30. Burning a collar returns the $PATCH held in its repair escrow: 20 for Common, 50 for Rare, 120 for Epic, and 300 for Legendary. Divine collars cannot be burned.
Three same-rarity Common, Rare, or Epic collars plus 50, 100, or 200 $PATCH can be welded into one collar of the next rarity. Deep in the Ark Server, 77 Divine dossiers wait outside the shared deck; redeeming one costs 1,500 $PATCH, and each of the 77 is a one-of-one. The 277 Legendary animals are one-of-one palette variants of five legendary bases, not copies in a crowd. Finally, a blue-check verified account on X may claim one free animal, once per X account and once per wallet, without using the 30-mint cap and without receiving $PATCH.
