"...I have done many horrible deeds... but perhaps, there still a chance to atone for my mistakes...” ~ Black Star, former Captain of the Griffin Kingdom Air Force.

Decades before the Equestrian War began. The Principality of Belka, a griffon fascist nation located just south of the Griffin Kingdom and east of the Crystal Empire accepted the terms of surrender and merged it's government with the superpower the Griffin Empire to become the latter's industrial state. The Griffin Empire thought that the merging between the two nations will gain some benefit, unaware of the seeds of hatred were already being planted inside the newfound state...

Just 20 years before the Equestrian War, a massive catastrophe engulfed the planet as an asteroid broke up into ten thousand fragments and impacted the planet, causing severe loss of life and structures despite multiple asteroid counter-weapons had already been built. The disaster caused the Griffin Empire to collapse and become the smaller Griffin Kingdom, which it's relation with the neighboring superpower Equestria became more and more strained ever since the disaster.

Now, ten months after the Equestrian War, the griffon Black Star who seeks atonement or his past mistakes find himself caught in the crossfire between the rebellious state of Neue Gryphus and the still recovering Griffin Kingdom. The crossfire quickly escalated into a war and every dark secrets behind the war may plunge the entire Equine world into chaos. What's worse, an old threat from the past may hadn't made it's final move...

Will Black Star find atonement for his mistakes? Or die trying. (MLP: FiM universe merged with Strangereal)

This is a spin off of PolishValsion's Ace Combat: Equestria Chronicles and I already had his approval to write this. Several characters from his fic will appear in the future.

His stories:
Ace Combat: The Equestrian War
Ace Combat: Wings of Unity

If you find any grammar or spelling mistakes, I apologize. English is my second language and I'm still not very good at it. (very)

The story takes place before the start of Season 3 of the MLP: FiM and it will focus more on the griffons rather than the ponies. The story takes several elements from Air Combat, Ace Combat 3, 04, Zero, 6, Northern Wings, and Infinity.

Just like PolishValsion's stories, there are music links on the chapters to provide a sense of atmosphere on the story. Just open up a new tab and listen while reading. This is purely optional of course.

This story is a sequel to Better Living Through Science and Ponies

THIS STORY IS CURRENTLY BEING REWRITTEN. PLEASE READ:
I've decided to rewrite this entire story. Considering that I began this project with almost no creative writing experience, I was bound to make some pretty bad mistakes. The story flow is not well organized, and there is an unhealthy amount of redundancy and poor pacing, as well as some pretty important things that I should have included. I intend to address these issues to the best of my ability, but it will be a long and arduous task. This story means a lot to me, so I want it to be more than the mere amateur mediocrity that it resembles. So, give it a read if you want, but keep in mind that it will change. I recommend that you put this on your read later list in the meantime.

This is a Portal 2 crossover. If you haven't played Portal 2, please do that first. Then read the prequel if you haven't done that either.

After Chell finally escaped the confines of Aperture Science, a freak portal mishap down below transported her, along with the entire Enrichment Center, to the land of Equestria. Upon entering this world, she was transformed into a pony. In a strange body and in a strange land, Chell was fortunate enough to be accepted by the ponies of Ponyville, and she lived out a new life contently among the ponies.

But that peace was not to last, for GLaDOS took a particular interest in the ponies of Equestria, and after two weeks of preparation, she launched a surprise attack and kidnapped 300 ponies to serve as test subjects, including Chell's friends and the princesses themselves. Once GLaDOS had them, she subjected them psychological torture. To save her friends, Chell made her way into the one place she hoped never to see again. In doing so, she freed the ponies, defeated GLaDOS in battle, and helped bring about the destruction of the facility. Although this made Chell a hero, she paid a terrible price in that brutal fight.

Beaten, battered, and traumatized, Chell spent months recovering from her wounds. After returning home from the hospital, all she wants is to once again live a normal life in Ponyville, but to do that, she must first heal from her wounds, both physical and psychological.

At the same time, GLaDOS herself has survived Aperture's destruction. With nothing left but herself, she vows to get back to testing. Though she faces an uphill climb, she is determined to see her facility rebuilt and the testing resume, and will stop at nothing to achieve this.

Has a TV Tropes page (will need to be updated after rewrite)
