A unicorn mare named Calidity Boreal just graduated from college with a Bachelor's Degree in Equinology. Her celebration is interrupted by a megaspell attack from the Zebra Nation. Calidity finds shelter in an underground fallout bunker called Stable 107. She spends the next 5 years in peace, meeting a half-zebra unicorn named Finder Keeper. Art the end of 5 years, the Stable is our in stasis, only walking the two unicorns up after about 200 years had passed. The world they return to us not what they remembered, but rather a cold, bloody shadow of its once colorful bliss.
