Galactica crossed the red line after jumping from the Cylon colony and found an unforgiving planet called Equus. On a world where humans and ponies reverse their roles, a top gun Viper pilot named Jennifer "Lunaria" Thatcher will have to choose between the Cylons and Colonials.

A Battlestar Galactica in Equestria crossover. If you don't watch battlestar, you won't understand some parts, though I'll try to do my best to explain all those crazy plot twists from the BSG universe.
