Twilight had no choice but to leave Starlight in the past after she rejected her offer of friendship. four months later she finds herself transported to the lair of the ancient "Grogar" where she's forced to team up with three other villains to get revenge on Twilight. Will she learn to work together with these three egotistical maniacs, or will she try to force equality upon them? Most likely the latter. Lol

Inspired by a post on the mlp reddit asking the same question.
