Desert Mirage lives in a world full of guns, lasers, explosives and people competing to be the best of the best. There she excels at what she does: hunting. She started as a nobody, and yet became one of the most sought-after gunslingers.

Sunset Shimmer was practically born the best of the best. Selected by none other than Princess Celestia to be her prized student... until she ran away to another world in search of power. Through trials and suffering she was eventually taught humility and friendship.

At first blush, they don't have much in common. But their connection runs deep, and sooner or later it will change their worlds forever.

Unhappy that her future as a member of the monarchy is denied by Celestia, Sunset Shimmer escapes through Starswirl's mirror into another world, planning to take it over to prove once and for all she was fit to rule. What she didn't expect—besides a species change—was to arrive in a world already conquered.

WARNING: CONTAINS SPOILERS FOR THE WHOLE STORY: TIMELINE

Graduation was supposed to be a happy day for the Rainbooms. Sunset and Princess Twilight had both agreed to temporarily shut the portal to Equestria so they could leave CHS safe and sound while they went on a post-graduation band tour. However, instead of SHUTTING the portal, they somehow made it explode, shattering the multiverse and scattering the Rainbooms across countless different universes. Now, Sunset Shimmer finds herself face-to-face with creatures straight out of dreams and nightmares, from the pages of legend to the screen of cinema.

Her best chance to reunite with her friends and get home: a self-proclaimed "Giant Nerd" and his old jalopy of a car, both of which are native to a world of silent observers of the multiverse, including her own life with the Rainbooms. Between his guidance and her courage, the two of them are determined to reunite the Rainbooms and get them back home...

Even if that means facing ink demons, xenomorphs, genocidal time-looping children, or even Egyptian god cards.
