Vault #: Vault 9 "The Canine Vault" as well as the "NOPE" vault
Location: Around [Probably outskirts] of Denver. Sign in front of it says "NOPE" in bright red luminescent spray-paint.
Status: Inaccessable
Occupants & oddities: 100-200 humans, the rest being domesticated creatures. Most of which consisted of dogs. Not much food was in the vault, but it did have a large surplus of tools to keep the vault running. And beyond the first layer it would cycled through seasons and weather. What occupants did not know was that there was some "wild" creatures included. All humans accepted were high-style fashionestas use to having everything done for them.
Layout: Origionally set into segments by layer. On the top layer was the living layer, but as you went down stairs each layer changed. The first layer one encountered would be a large, foresty area with fake trees and fake grass. This area was home to wolves, large deer, small bears, wild rabbits, jackrabbits, wild birds, and birds of prey. In the center it included a large fresh-water small lake.
The second layer was a desert terrain, which included: coyotes, rattle snakes, scorpions, large bugs, large arachnids, desert turtles, and small oasis all about.
The third layer was swamp-like, highly irradiated, and stuck in forever-night. In it was: large mutated crocadiles, large [nocturnal] mutated birds, oversized arachnids, large snakes, and finally many parahnas.
Goal: How long could man's best friend stay man's best friend? What happened if dogs bred back with wolves and coyotes? How would a group of "nobles" chain together in the events of a civilization?
Notes: After some time the humans begun to use the excess parts to place into their companions as well as themselves.
Succes?: After some time most of the humans had died, leaving a large ammount of wild wolf-coyote-dogs became feral. One day the large dog population busted into the upper floor. The humans, needing to escape, opened the vault and did as such. They brought with them many supplies for science and creation, and fled into Denver along with their companions. Of the few who know of the Vault's existence, many say this is why the area is flooded with dogs. The occassional cyberntic dog being a companion to one of the humans who didn't make it and died in Denver.
To stop the surplus of wild creatures and especially feral dogs from breeding and continuing to flood Denver, many of the humans in a last-ditch effort ran to the Vault and shot explosives over the crater above the vault, resulting in its enterence becoming covered with rocks.
