When a temporal rift manages to transport The Doctor, Commander Jane Shepard, and Dr. Gordon Freeman into Equestria, they will learn that they're only the first in a long line of "guests" to the land. Having learned this they now have to gather together to save everyone from inter-universal armies, gathering as many allies possible, or else all of reality as they know it will fall under the oppressive rule of these armies, or worse, destroyed.

Author's Note: HiEs are overdone. There are a few good ones but now it's like getting really good toast with an overall bad breakfast. But this isn't an HiE in a traditional sense so it's all good. I was never that big a fan of reading crossovers, but I kind of want to try writing one. Equestria is just sort of the canvas; the fun comes in the crossovers. I wondered how many crossovers I can get where the story tap-dances on the line between awesome and ridiculous. Good vs. evil story. Also, I will maybe try to attempt editing my previous chapters to make them well... better, or at the very least less worse.
