King Sombra believes that if he, Luna, and Discord can change their ways so can Lord Tirek. King Sombra sets Tirek free and made him the Colonel of the Seleneville Guard. King Sombra has also gifted Tirek powers to test him. Tirek later meets a beautiful Centauress and the two bond over time. Little does everyone know that there is an evil greater than Tirek, the evil Discord, Queen Chrysalis, the evil King Sombra, or any other villain or former villain put together waiting to be set free. Tirek, even though he won't admit it, slowly comes around and earns almost everyone's trust as he and the others have many adventures, meet new bad guys, good guys, and others that were mentioned in the prequel, The Redemption of King Sombra, along the way.

King Sombra has revived himself and seeks redemption. Along the way he makes friends, started giving and caring, and finds a mysterious Dragon Egg he somehow left in the Crystal Empire before his defeat. He does not remember why he put it there, but he takes care of it. King Sombra, the Mane Six and the others have many adventures, meet new good guys and bad guys, make new friends and some may even find some love. But what is that Dragon Egg?
