Great Crystal War

The Great Crystal War is a war waged between Equestria and the Crystal Empire in an alternate timeline created by Starlight Glimmer. It is featured in the season five episode The Cutie Re-Mark - Part 1 and Enterplay's collectible card game.
==Depiction in the series==
 In The Cutie Re-Mark - Part 1, Starlight Glimmer uses Star Swirl the Bearded's time travel spell to go back in time and stop Rainbow Dash from performing her first sonic rainboom. This sets into motion an alternate chain of events, beginning with Twilight Sparkle and her friends not earning their cutie marks.
Years later, the Crystal Empire reappears in Equestria's Arctic North, bringing the evil King Sombra with it. According to the Applejack of this timeline, Sombra then retakes control of the Empire and wages war on the rest of Equestria, using mind control helmets to force the Crystal Ponies into his army of soldiers. Over the course of the next several months, the Crystal Empire's borders expand across Equestria, including the San Palomino Desert, the Badlands, and portions of Griffonstone.
Princess Celestia and her subjects fight back against the invading Crystal Empire. The royal guards, Wonderbolts, and other ponies are enlisted into Celestia's army, serving as either soldiers or war effort supporters. Meanwhile, Princess Celestia's research mages look for a counterspell for Sombra's mind control helmets.
The Twilight Sparkle and Spike of the series' main timeline briefly visit this reality and bear witness to the effects that the Great Crystal War has had on Equestria. They depart from this timeline before the war's resolution.
