This is a story not a whole lotta' ponies know. It's a bit of forgotten history, a story obscured by shadows, a story Discord himself eagerly wants to forget.

It's a story about when Equestria was under Discord's rule the first time. It's a crazy day like usual, but something unexpected happens, caused by a silly mistake...

Discord...Becomes nice.

Reincarnated as a pegasus, Discord is somehow brought into another dimension. Here, Ponyville is called Jadeite. Here, everypony seems crazy and nobody believes Discord is who he says he is. Here, not everywhere is ruled by Princess Celestia.
It's weird to think, but being a statue is better by comparison! But how is he to get back?
