After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

Ponies have spread to the stars thanks to advances in technology. In the advanced and luxurious Solar Explorer, Celestia travels to the first extra-solar colony world set up by her little ponies. Unfortunately, events elsewhere in the galaxy, unknown to them, have set in motion a cycle that has been repeated for countless eons… the reaping of sentient races. A Reaper dreadnought confronts the Solar Explorer, intent upon indoctrinating the leadership of the ponies and bringing them to heel.

Said Reaper quickly learns exactly why Celestia has earned the title Unconquered.

A Mass Effect crossover oneshot.

This story is a sequel to Upheaval: Reckoning

Equestria's fragments have reunited, and the power of sunlight shines once more within Celestia. With the remnants of the Old Kingdom destroyed, the Abyssal Throne sent away, the threat of Gravitas defeated, and Black Rose no more, Equestria now faces the encroaching darkness of Oceanus and his rebels.

But the stage is not yet fully set. Twilight Sparkle and her friends must gather what means they may before the battle is joined.

Equestria is a vast place with many corners that remain unexplored. For most the pursuit to fill in the map is driven by an urge for knowledge, prestige, or wealth. Although, in the case of Twilight Sparkle and her rival Trixie, it all started over an impulsive bet.

So join Twilight and her crew as they travel the world aboard the airship Discovery, in a quest to explore the unseen, discover new things, find fabled treasures, and one up that egotistical showmare.

Oh, and try not to get sweet talked by cannibals, killed by cultists, or scared off by dashingly handsome highwaystallions.

This fic is inspired by the game Renown Explorer: International Society.

Monsters, they're not real right? Well they are, but that's not a very widely known fact. They have stayed hidden for a long time. Until that day. She crashed, straight into the Everfree. She got the 'Blessing' the mother called it. But that doesn't mean Rainbow Dash thought so. Because she was the one, the one to be 'infected', giving her advantages, but it made her something else.

There was only one explanation. For all of it. All of the strange, erratic behavior. Her irrational fear of the sun. Her nocturnal habits of locking herself in in the dark and closing all the blinds. Wearing her sunglasses everywhere, even inside! It was time to invest in some silver, garlic, and a wooden stake.

This story is a sequel to Where Loyalties Lie: Honor Guard

Honor Guard Captain Red Ink is a proud warrior, the son of the Stalliongradi Tsar, and something of a legend amongst the Equestrian Guard. Until his mistake, some would have said he was atop the world. But a reckless violent streak and a disrespect for the common pony carry him away from his lofty post aside Celestia.

He expected a frigid post on the dragon border to carry the rest of his days. Compared to that fate, delivering a letter to the Princess's student in Ponyville seems a delightfully easy task. If he had known the fate the Princess had prepared for him in the tiny city, he might well have exiled himself. Fate can be cruel indeed to a warrior staring down at a nearly blank piece of parchment, knowing his life depends on filling it with words. The beginning, after all, is always so very easy.

"Dear Princess Celestia..."

A Price of Loyalty story.

A spin-off of Where Loyalties Lie, though you don't need to have read it.

This story is a sequel to Where Loyalties Lie: Honor Guard
