The souls of the dead slowly wake from their peaceful sleep and one by one another soldier rises and the grave's begin to empty. The army of The Shiv come slowly but surely and there may be only one pony who can stop them. Fighting with trial and error, time and Magic, Starswirl risks heading back and forth through time to warn himself and the Elements.
Deleting and rewriting the future, past and present is the only way to save those who have died fighting the war against the dead. The Shiv and his army will go through anything and destroy anyone to continue the pursuit. Starswirl, the Elements and all of Equestra have a choice to either join The Shiv's many ranks or risk certain death fighting them.
