The immaterium is an unpredictable and fickle aspect of reality, and "impossible" ceases to be a valid term when it is involved.

As such, when Twilight witnesses a fantastical cosmic event occur above Equestria, she immediately investigates. What she finds is nothing short of one of the most dangerous artifacts to ever make its way to the relatively peaceful realm of ponies: a blackened suit of massive armor, marked by the ouroboros.

Warhammer 40,000 crossover inspired by Blooms in the Dust.
Now with a sequel, Forged Anew!

In the aftermath of the Changeling incursion of Canterlot during the marriage of Shining Armour and Princess Mi Amore Cadenza, Equestria gears itself for war against the Changeling menace. Against a foe that can take the shape of anypony, assume their life, and undermine Equestria from within, the Royal Pony Sisters create a new institution to monitor their Royal Guard for any Changeling corruption, cowardice, and incompetence: the Commissariat. As total war rages across the land one hero stands out above the rest; Commissar Blueblood, Hero of Equestria. Or at least that's what the propaganda says. The truth, as ever, is far more complex, as the esteemed Blueblood is merely looking for an easy and sedate life. Unfortunately, fate has a habit of throwing him into increasingly dangerous and suicidal missions, which he must survive with a combination of self-preservation, lying, and sheer blind luck, even if doing so only fuels his soaring reputation!

Equine military fiction in the style of Ciaphas Cain and Flashman.

Mis-communication has started many a war, but in this case maybe calling it a war was too generous.

The "war" is over, Twilight has successfully orchestrated a bloodless end to the Griffons' aggression, but only now does she realize that there is more to winning than she had first assumed, especially against a nation that holds war as a central part of their culture...

Now Twilight must deal with the aftermath while facing a challenge she never anticipated: being seen as a conqueror.

This can be read alone, but I recommend reading the letter that started it all for a chuckle and a little exposition. This series of expositional one-shots can also give some additional world-building.

In response to threats of a griffon attack on Equestria, Twilight responds with a letter detailing just why such actions would prove unfavorable for them.

ACT One: (Chapters 1-10)
After a fatal tragedy, Twilight wakes up in a situation unlike anything she had experienced before. How is she supposed to react when she finds herself reincarnated as the daughter of Queen Chrysalis, the very one who orchestrated her assassination? Does she give into the rage and loss of her former self, or does she hold true to the magic of friendship?

ACT Two: Synopsis incoming

Princess Twilight Sparkle discovers a fact about alicorn reproduction she never expected.

So do the other princesses.

Editors: Pascoite

Strongly Recommended Stories:
The Brightest and the Best by Pineta - The events in this story are considered to be completely canon to this timeline and explain Twilight's entrance exam to Celestia's School for Gifted Unicorns. I cannot recommend this story enough.
MLP Annual 2013 - "The Fall of Sunset Shimmer" - As above, the 8-page short comic in the beginning of the Annual is also considered to be canon, though with some major variations.

Version 3.0 Edit: Extensive grammatical and mechanics changes. Adjustment to timeline of Sunset's second mirror experience.

Shining Armor and Cadence's spell reveals something completely unexpected as it expels Chrysalis and her changelings out of Canterlot: A secret kept from everypony for several years...

Now with a TV Tropes page! Warning: Will Contain spoilers.

This story is a sequel to Dead/Light

Twilight's life definitely took a strange turn when she died. Of course, this won't stop her from living it to the fullest, whatever that entails.
Equestria will never be the same.

After the first, chapters will alternate between serious ( - ) and silly ( ~ ), because I didn't want the story to be limited to just one. Most will be standalone, and in no kind of chronological order; expect little correlation between chapters and occasional verb tense changes from one to the next.

This story should be considered in perpetual hiatus, as it will rarely be the focus of my attention. Do not expect regular updates.

Rated teen just to be sure. Cover art made by this butt.
