The Equestrian ponies live in a state of fear, under the hooves of a pair of terrible tyrants.
Many wake every day, only to run for their lives, seeking some safe hiding place. And they are the lucky ones.
Others are slaves, forced to work, fight, and die, with no hope of freedom.
Some want to fight back, but none seem to be able to stand against their oppressors.
And still others seek refuge, going to the one being in Equestria that can help them. A Spirit of Chaos, named Discord.
Very alternate universe story, in which the characters' moralities are reversed.
