As things begin to settle down in Ponyville after the recovery of the Crystal Kingdom, Twilight Sparkle receives a message telling of another civilization. She and her 5 friends must journey to a new horizon, a city of ponies that possess technology far more advanced than that of Equestria. If everything goes as planned, Equestria could gain a very important ally, or their most feared enemy. All seems to go well until three curious fillies that belong to the club of The Cutie Mark Crusaders sneaks into the city and are caught, they threaten the whole mission. A war with steamponies is the last thing Twilight and her friends want. If you like steam, and if you like, ponies, hopefully this is the story for you!
