so on one of my first fallout:Equestria stories i made up a stable zero thinking it didn't exist in fallout but turns out there is a vualt zero and it is exactly like the one i made and i had no knowledge it existed
Well Vualt zero was inside a mountain my stable zero is under canterlot which means it is also in a mountain. Vualt zero put pre-war inhabitants into cryo sleep,stable zero put it's inhabitants to magically induced hyper sleep. both malfunction and Kill most of their inhabitants.
