Many years pass.
The secondary character, the capitalist, Roseluck, the dark emperor, what have you, rules the land that was once Equestria for centuries, undisputed.
Eventually, new heroes arise, and overthrow him, banishing him to an endless abyss, that he may never return.
As for the original, Alpha Roseluck? She stays in the illusory time loop forever more.
The End.
