The Stalker universe... only this time, set up on Equestria.

Even after numerous years, Equestria still suffer from the results of the accident. roads are covered by dangerous anomalies, forests are inhabited by monstrous creatures... but there are also marvelous treasures to be found, trinkets with amazing proprieties called artifacts. A pony could get rich or dead real fast.
But what is this "The Zone" place that Equestria has been turned into? many consider it as a source of abhorrent and threatening dangers. others, a marvelous gift sent by the gods. some other ponies say it is an opportunity to cash out bits , and even others, consider it just their home.... But to what point are these descriptions true?

Though the history of Equestria has always seen as a peaceful thing, the truth can seem like a mere fiction. But the truth is always hard to accept.
Long ago, many years before Equestria was as peaceful as it is now, Celestia and Luna were princes to a Warrior Pony, King SoulStorm of the Central Empire. But as they soon find out, their father's hidden agenda is to rule Equestria through the help of the malevolent figure, Discord. Forced to abandon their simple lives as mere princesses, they must find help and raise an army to fight back the evil that threatens to consume all of Equestria.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

It is the year 2552 and the Pillar Of Autumn has just entered Slip space to escape the Covenant fleet at Reach. A malfunction occurs with the Slip space drive and sends the Autumn and her crew into unknown space. The first planet that comes into range is very Earth like, and is giving off intelligent life signatures. What they don't know is that their only way back home is on this planet. The Autumn dispatches a scout party and what they report back is unbelievable. A world completely inhabited by ponies, millions of them..... Welcome to Halo: Equestria.

I'll add in more character tags as they are introduced in the story.
