Previously known as; The Forgotten Empire of the Time Before.
An ancient Empire known as the; "Crystal Empire" back in its day that had vanished from Equus as well as a huge portion of the 'original' Crystal ponies, this Empire had a King, and two Princes all three of them related and the two younger ones betrayed their older brother when he waged war against the newly formed Equestria. Those two younger Princes where; Prince Dawn Star Blade who went by Dawn Blade, and Prince Ruby Magic Light who went by Ruby Light, both who joined Equestria with their most loyal friends, both being of Alicorn blood, but at the end of the war Star Blade vanished along with the Original Crystal Empire. The new Crystal Empire reveals its' self to Equus and the Original Crystal Empire's Crystal ponies were the original creators of the Crystal empire but their blood got weak and only a few things are the same as their ancestors. Now 5-milenia later the Original Crystal Empire re-arises and the two Princes of that empire who vanished now reincarnate with their old destinies and their new destinies and now a war between the two Kingdoms returns and the first war Equestria has ever had since the olden times.
