This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

Brought to you by Loyal2Luna, this new Downloadable Content for Mass Effect 2 brings the fight to Equestria.

Just about ready to embark on their mission to stop the Collectors from further abducting human colonies, Commander Shepard and the crew of the Normandy SR-2 are given a new priority, when the Illusive Man tasks them with investigating the mysterious disappearance of a Cerberus science team.

Soon, what begins as a simple search-and-rescue unveils a mystery millions of years in the making, and the Commander finds himself thrust into a situation he couldn't possibly have prepared himself for.

Join the Hero of the Citadel as he uncovers the secrets, combats the demons, and ultimately decides the fate of the impossible world known as "Equestria."

Stormbreakers live on the coast of Equestria, and fly out to sea to fight feral storms that approach the mainland. Sometimes they don't come back.

Aurora Mist's worst fears are realized when her team comes back one mare short.

Side story to Starscribe's fine work The Last Pony on Earth. The main character was on vacation when the Event happened and hands were replaced with hooves. An attempt to find food & shelter is made after the apocalypse.

Now with 100% more cover art! My good friend Lionheartcartoon, also known as half of the creative team on the PMV "Children of the Night", happily put this together for all to enjoy.

“My daughter Celestia, look at me. I love you, and I wish the best for you in the eons of labor you have yet to endure. So heed my words. When we planted light upon the fields of Creation, Celestia, it was a divine thing. But there will come a time when our brilliance won't be enough. It will take a great, unknowable darkness to test the luminescence that we have bequeathed life. That is an abyss that we can never, ever follow our children down, no matter how much we love them.”

A Silver Medalist of the Ponychan /Fic/ Write-Off: "Cutting Ties"

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."

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.
