The reign of Dragon Lord Torch has come to an end. With his daughter, Ember, having inherited the title, he resigns himself to die in the heart of a volcano.

That is until, five years later, he awakes to the sight of three mysterious ponies. They are the Cult of the Dragonflame, and they fully intend to restore Torch's rightful position of Dragon Lord. In doing so, they will help to raise an army of undead dragons, all for the purpose of waging a war of conquest and destruction across the whole of Equestria.

Can Equestria's newest Alicorn, Stellar Shine, ammount a force strong enough to resist the undead hordes? What will this mean for the future of dragon and pony relations? And what is the Cult of the Dragonflame's true goal?

Only time will tell, now that Equestria is on the cusp of the greatest war the kingdom has ever known.
