The 7th part of the Terror in Equestria Series.
The Great War is over and the allies believed that the world would return to being peaceful again but an unpleasant surprise appears in Equestria as old foes, once thought to have been vanquished forever, will return. A defector from Ponyville will travel abroad to warn Colgate and her allies of what has happened. This pony will join Colgate and her allies in the battle to re-take Ponyville and liberate the ponies of the world. The results of the final battle will not only determine the fate of the ponies of Equestria, but every living thing on the planet.
This is the story of how Equestria, the land of love and harmony, finds itself in a war against a dark alliance that seems unstoppable.
The Dark Queen Twilight has just cemented herself as the sole ruler of Equestria. She is extremely powerful, but she wants a power only the Goddess LaurFa had, to see all. To achieve this, she must acquire an ancient relic in a guarded city.
Twilight now has the Jade Alicorn and can see all over the world. She has absolute control over Equestria but she thirsts for more. Will she conquer the whole world or lose everything?
Shortly after completing her conquest, Twilight and her brother begin to travel more often leaving Colgate in charge a lot. Colgate decides that perhaps she should rule full time.
Celestia and Twilight finish their sentences on the sun and Twilight wants to rise to glory once more. She first must convince Celestia and other powerful ponies to help her to have a chance to do this.
3,000 years have passed since the unmaking of evil. The world has lived in peace and harmony but the assassination of two high level officers near and international border will bring that peace to an abrupt end.
The Great War is over but peace will not return. Old evils, once thought to be gone, have returned and want control of Equestria. Colgate will fight to keep her nation, but will face an enemy she never expected to see again.
