An undead Emperor in need of a new body. A Spartan lost in space. A ragtag team on a suicide mission. What do they all have in common? They all wind up on the magical world of Equestria, where war has been forgotten. That, however, is soon about to change.
When each of them is about to be retrieved, ancient evils arise to unleash hell upon the unsuspecting world. When the forces of three galaxies clash around them, can our favorite ponies hold out against the onslaught?
This is a crossover involving Warhammer 40k, Halo, Mass Effect and MLP, and is also my first fanfic. Comments and reviews are welcome.
Rated T for language, violence, and general adult situations.
Now on Tv Tropes!

Starlight Glimmer is repentant, on the path to reformation after she saw what her plan could have caused. She was thankfully talked down, all the possible futures she made prevented, all the changes to the past no longer existing.

At least... that's what everyone thinks. But magic isn't something to be abused.

There are always consequences.
