Stable 1 was a fallout-bunker built to allow ponies to survive in till the surface was safe again.


Though seemingly meant for the elites of Canterlot, as well as royalty, the Princesses and the Ministries, Scootaloo had secretly rigged it to be a prison instead, as she blamed them for the pony-zebra war which had consumed Equestria. She designed the stable to keep its residents alive, but unable to open so they would be trapped for an eternity.

Scootaloo's plan never came to fruition however, as neither the princesses nor the ministry mares entered it in the first place. The stable was later looted by the Ghouls of Stable City.
