Vault 32

Puggsly - The Enclave intended to use the Hermes-13 spacecraft from Van Buren to escape Earth. They found it overly expensive to produce the freezing conditions of space and life on a spacecraft running on low power without great cost, but the Vault program provided a long term solution to this problem. Vault 32 was built to slowly turn up heat over generations, to create a group of people acclimated to sweltering temperatures full time. Snow Vault Suits were provided to the dwellers under the ruse of defending against Nuclear Winter, which they were told would last forever. When the people of the Vault came back to the surface, they found bizarre "Frostwalkers" who could easily survive the bitterly cold wasteland with ease. The people of the Vault rarely send out away teams to scout the surface, instead prefering to live amongst their own. "Issues" with the Enclave mean that they have never come back to their guinea pigs, who continue to function well past intended. Maybe one of these guys could make a good companion, to have a sort of "fish out of water," buddy cop situation.
