This story is a sequel to A Stitch in Time

Having discovered the message left for her by Star Swirl the Bearded in the distant past, Twilight once again finds herself caught up in the middle of a struggle against forces far greater than herself. In order to even stand a chance she'll need to travel further and wider than she ever has, and forge some unlikely alliances with old enemies. All to bring down the powers that have manipulated and shaped her entire life, and retake control of her own future.

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."

The past always comes back to haunt the present, there is no escaping the inevitable. For decades, Celestia has kept a secret from her student. A secret she made out of pain, and through pain will be revealed for all to see; for Twilight Sparkle is the secret daughter of the Sun.

Now, there will be consequences.

Consequences, they come in all shapes and sizes for every decision. For every action there is an equal and opposite reaction. These words are lessons that Princess Celestia should know, bits of wisdom she practices in her rule of Equestria. How is it then, that when faced with a decision, she chooses the one that would inevitably bring the most pain? How is it that she couldn’t bear being recognized as the mother of her child? And why? Twilight Sparkle is about to find out.

Twilight's abilities stem from her Gamer power which makes her life like an RPG. How will this affect her life? Let's find out!

A pair of sisters awaken to a Utopia among the stars, one eager to explore yet wary of the changes wrought both upon the world she once knew and within her own mind. The other intimidated by a world far larger than she could have ever imagined and eager to once again walk among the living.

They are known as Luna and Celestia and in this new Equestria they have been made redundant.

A woman who was once a pony known as Bitter Leaf, DCI to the city of Appleseed was found murdered in a back alley. Resurrected through the wonders of technology she is given the task of tracking down her killer. However strong evidence points to foreign espionage, important technology has been stolen and if it isn't recovered covertly then it could spark a conflict between two of the most powerful star faring civilizations in the galaxy.

The projected casualties are measured in the billions.

Twilight has been assigned by Princess Celestia to study Dark Magic, something that has almost virtually died out. One day, halfway through her assignment, she receives a surprise visit from the Princess herself, who gives warning that dark and trying times are coming, and returns home. A confused Twilight then begins searching for large problems, both inside Equestria and out. When she discovers a major threat that nopony is prepared for, things quickly go downhill. Equestria seems doomed to total destruction, until a hooded pony appears with an offer. An offer that could either save them from catastrophe, or make things much, much worse...

Story is canon until Twilight becomes an Alicorn.
