Most ponies, when they see a pony with an hourglass cutie mark, would figure that it would mean their talent has something to do with time, or clocks, or another harmless meaning. Technically, the first is true, but there is a hidden meaning beneath it. To those that carry it, they know that the hourglass marks them as refugees, survivors from a war that would make any normal pony go mad from glimpsing just a fraction of the sheer scope of it. These unusual ponies have all found asylum in Equestria, but now, one last escapee will be followed by an evil that will threaten to ignite the conflict anew and bring down their last refuge with it.

But this newcomer not only brings the remains of the conflict with him, but is their best and only hope of ending it once and for all.

The last gasp of the Time War has come to Equestria. The Doctor will find old friends, make new ones...and face off with one of his greatest foes, one last time.
