First contact. Not just with a new world, but with a world in a whole new universe. Initial negotiations go well, so Princess Celestia makes a visit to this 'Earth' to cement peaceful relations. Unfortunately, even when you are as experienced as the goddess of the sun, it's the little things that can trip you up.

Imagine a world (or a crackfic) where everything you know of the ponies is true. Now imagine the ponies living in the universe of Mass effect where magic is just another name for biotics.

The Reapers are coming, but they have never faced anything like the Ponies.

Well it's not actually a sequel. Here is a collection of short stories and histories detailing the life of Alternia, a changeling queen impersonating the life of Princess Celestia. These are the stories of the ruler under her mask.

Reading the main story: Princess Celestia: The Changeling Queen is a requirement if you don't want to be spoiled or confused. I will try to provide background information when I can.

For readers of the main story, there are basically no spoilers if you've read past chapter 8. Enjoy!

This story is a sequel to The Sun Burns Brightly

When you're the immortal ruler of an entire kingdom, the most important quality to possess is a passion for your work. No princess can rule her nation if she can't find it in herself to give her best effort every day and night. Luna knows this better than anypony, and puts her whole heart into everything she does.

But passion, unless tempered by restraint, has a way of biting one in the flank.

This story is a sequel to The Moon Glows Gently

When you're the immortal ruler of an entire kingdom, the most important quality to possess is self-control. No princess can rule her nation if her emotions rule her. Celestia knows this better than anypony, and mastered them long ago.

So long ago, she may have forgotten that a little bit of passion can come in handy now and again.

This story is a sequel to Princess Celestia: The Changeling Queen

This story is a direct sequel to Princess Celestia: The Changeling Queen. Reading that first is necessary to understand any part of this story.

Alternia, sister to Chrysalis, ruled Equestria for a thousand years, disguised as Princess Celestia, while the alicorn slumbered in a healing sleep. Now revealed, Alternia prepares to become Equestria’s first changeling princess, and prove herself to the ponies she loves at the side of her co-rulers Luna and the newly-returned Celestia.

But even as the crown descends onto Alternia’s head, something is stirring in the depths of the Eastern Sea, something that will turn the surface world onto its head. Some power that could destroy Alternia, and all that she loves, before she can even regain the approval of her own ponies.

Will Alternia restore the trust her ponies once placed with her? Will she found a hive? Will she find love?

All that is certain is that Equestria, and the world, will never be the same again.

Now with a TV Tropes page.

On the anniversary of her presumed death, her friends gather at her memorial. What was suppose to be a day of remembrance was shattered by a strange metal object that landed right beside them. Their anger quickly turns to shock as a familiar unicorn emerges... and boy does she have a story to tell.

Straight from the Canterlot archives, this collection of documents retells the rise and fall of Princess Twilight Sparkle, Enlightened Despot of Equestria, Defender of the Peace, Lawgiver, and Commander of Fort Libris.

Twilight Sparkle is, of course, known to historians as the first usurper to seek to schedule a coup d'etat by appointment. But for other details- such as, "What is the longest recorded time a pony has gone without sleep?", "Is it true what they say about swans?", and, "Why is there an owlbear in the Equestrian Witness Protection Program?"- these documents provide the answers and much, much more.

This is ABSOLUTELY SERIOUS HISTORY from primary sources. If anything makes you think this is silly, ludicrous, or unbelievable, blame Discord.

Written for FanOfMostEverything's Imposing Sovereigns writing contest.
