Two years have passed ever since Sunset Shimmer saved Equestria from the Alliance of Darkness with the Order of the Stone. Due to changes of duty, the Order disbanded, leaving the sorceress alone and having only herself to depend on. That is until she has a dream telling her to gather the rest of the Order and head back to Equestria. After she is successful in doing so, she and the Order travel back to land, only to find it engulfed by a dark cloud. The group falls into shock and curiosity until they learn that a horned man called the Storm King has invaded the land, putting all of Equestria at risk. Now, they must save the land once again with the Guardians of Equestria and a visually impaired deserter who knows more of the Storm King than any of them.
