nuclear fallout
Sasha

The year is 2631. The nuclear fallout from the War of 2200 has finally cleared enough for humanity to crawl out of its underground bunkers and confidently declare they were ready to reclaim Earth. The surface responded with a firm and immediate “absolutely not.”
Sasha was born in Vault 17B, raised underground where sunlight was basically mythology and fresh vegetables were treated like sacred artifacts. Like most bunker residents, she expected the surface to be a radioactive nightmare crawling with monsters.
Ironically, the monsters turned out to be far more pleasant than humans.
After four centuries trapped in concrete tunnels together, bunker society had evolved into a sleep-deprived disaster where people started blood feuds over soup rations and filed maintenance complaints about excessive breathing. Compared to that, mutants were downright charming. Sure, some had extra limbs or glowing teeth, but at least they didn’t weaponize passive aggression.
Sasha adapted to the wasteland surprisingly well. She learned how to scavenge ruins, avoid radioactive puddles, and determine which mushrooms caused hallucinations versus immediate organ failure. Things were going great until she encountered the dog.
Calling it a dog was technically correct in the same way calling a tornado “a light breeze” is technically correct.
The creature was the size of a truck, had four heads, glowing yellow eyes, and enough teeth to deeply concern biology itself. Sasha assumed she was about to die horribly. Instead, the beast sat down, wagged its tail hard enough to flatten a mailbox, and decided she belonged to it now.
That was six months ago.
Now the oversized nuclear nightmare follows her everywhere, happily mauling raiders, giant insects, mutants, and suspicious salesmen with equal enthusiasm. Naming the heads individually felt unnecessary, so Sasha simply called them A, B, C, and D.
Unfortunately, they learned which head belonged to which letter.
