Out of the many vaults that inhabit the nuclear wasteland that once was the United States, many more "private" vaults were also created. Vaults not known to the public. One of these vaults specifically kept some of the most dangerous and aggressive criminals in the US. It was known to its inhabitants as Vault 140 They were testing a different strand of FEV (Forced Evolutionary Virus). A strand that was built to find docile and make the recipients calmer, simpler, and more easily manipulated. 150 years of research and testing got the scientists nowhere, but the convict's descendants kept the traits that their parents and grandparents had. They rebelled against the scientists in the vault and took it over. They opened the giant door that led to the wasteland, and the first thing that hit them was the cold. The bone-chilling cold.
Vault 140 was located in what used to be Quebec, Canada. The city surrounding it was dead, and frozen. The people of Vault 140 realized that it would be almost impossible to escape to warmth without being frozen first. There was no protective gear in the vaults, no way for them to keep the cold out. They would have to stay in the vault, until they figured out how to escape. 20 years past and many of he people attempted to leave, all never returning and presumed dead. The vault continued on with its life until one strange day. The day where a visitor arrived.
The visitor was not a human, not one of the people in the vaults. He was a ghoul, a person so irradiated their bodies are corpse-like in quality. He told the vault-dwellers his story, of how he was looking for a descendant of his bloodline. His brother's descendant. The ghoul's name was Kennedy, and his brother was a cold-blooded serial killer. Kennedy told them he needed the youngest child of his brother's bloodline for a special task. A task he refused to tell them of.
The vault-dwellers brought the youngest child in Kennedy's bloodline forward. His name was Asher, and Kennedy smiled as he tousled his hair. He asked only of one thing from the vault-dwellers, a minute alone to explain to his great grand-nephew his purpose. The vault-dwellers left the two alone and Kennedy rasped into his ear, "Your great grandfather was special. He had something inside of him that no one else did."
"What?" said Asher.
"His best work was as a child, and the government before the war secretly found him out. Oh, it was hard for them but they found him and brought him here.:
"What did he do?"
"He made sure to satisfy a hunger that he kept inside himself for so long."
"Sometimes..I feel like I'm missing something. Like a part of me is wrong, and I need to fix it."
"Then it is good I brought you this," Kennedy pulled out a brown package from his backpack and handed it to Asher. "This is yours now. It is your duty to feed your hunger. My brother wanted me to pass this on and now that I have its time for me to get out of here and make my own life." Kennedy moved towards the control panel and opened the vault's door. The huge gate crashed aside and Kennedy exited the vault, but not before winking at Asher.
The other vault residents came in and found that Kennedy was gone. Asher hid the package as he told them all the ghoul was just a freak. Wanting nothing more than to have his way with the young boy. Asher said he declined and the residents sighed. They all went back to the humdrum ways of vault life, all except Asher. He went back to his room and opened the brown package, and inside was a mask. A clown mask, and a knife. There was also a note. You are my blood, so spread as much as you can of others. You are now the Pint-Sized Slasher, no one else. Asher grinned as his smile reached ear to ear, he wouldn't be hungry for much longer.
