A suit of armour wakes up in the woods from a very long nap and has some issues. These involve some less than stable quadrupeds called ponies and one very specific one which we shall refer to as Luna.

Rainbow Dash's morning was pretty much ruined.
She tripped getting out of bed and landed flat on her face, giving herself an aching muzzle.
She forgot to buy her favorite brand of hay flakes at the store yesterday and had to eat plain toast for breakfast.
She found out she had to pull double-duty today and tomorrow on the weather patrol.
Oh, and she found a nearly-dead foal, broken and bleeding at the edge of Ponyville.

The rest of her day became a whirlpool of stress and worry but the colt woke up, thank Celestia.
Something's not right, though. Nopony can find his parents, he's not in the registers, and there's an unsettling look in his eye...

Anon and Luna find themselves engaged after a night of drinking. Neither are too happy about the situation.

Nightmare Moon's return was not without incident and injury. Those that were chosen by the Elements suffered and were pained in the attempt to save Celestia's younger sister. While they succeeded, the trial left scars.

Princess Celestia sees this as everything going as planned and is ready to use the new Bearers for anything she needs taken care of.

Princess Luna thinks the group should be protected and only used when the situation is at it's most dire.

A compromise is made and Luna is allowed to form a team to deal with threats that do not require an orbital strike from a friendship canon. Provided she can find those willing.

With the memory of Nightmare Moon still fresh in every ponies mind, Luna is unable to find ponies who are willing to serve her readily.

So what is a Princess of the Night to do?

Not recruit ponies obviously.

What if a fan of My Little Pony was suddenly sent to the world of the show, before Equestria was even founded? In an attempt to get home and survive tribal pony society, Astraeus must enlist the help of the royal sisters before they've ascended.

Can he return to his family without permanently ruining the sisters' future and that of all of Equestria? And will he be able to resist using his knowledge of both the show and modern technology to help his new allies?

This story is a sequel to How Blueblood Jumped Out of a Window and Got a Promotion

Managing to not only prevent Luna from finding out what he'd said about her, but to also convince her that he'd saved her, had been undoubtedly one of the greatest achievements of Blueblood's carrier. Now, he was going to be rewarded for his wits by becoming the Princess' personal student, a path that would lead him to eventually become an alicorn.

There was only one, minor detail he hadn't accounted for. In order for him to become an alicorn, he would have to be Luna's student. It wasn't something he could back out from now that he'd accepted. It wasn't something he was prepared for. Unfortunately for him, Luna wasn't prepared, either.

Reforming the tax and legal system had been her responsibility a thousand years ago, and it will be so again. There have been many changes during her millennium of absence, but the fundamentals always stayed the same. Ponies would find ways to circumvent the laws for their own benefit, and it was her job to make sure that didn't happen—in the most direct way possible.

Matthias Síðasta Von has always wished to visit the magical land of Equestria, see the wonderful colors, talk to the ponies that live there. Perhaps even, should he be so lucky, live there permanently. Help Fluttershy with the animals, listen to Twilight talk about her most recent lesson or experiment, lift baskets of apples with Applejack, tell Lyra about humans.

One day, a connection is made, an offer: step through the gate. It was warned that the cost might be hefty, that the journey might be hard, but anything was better than this drab, grey life. So he stepped through.

But, this is not the Equestria he knew. Buildings aged and decrepit, roads cracked and eroded, the Everfree slowly reclaiming the Apple's farm and the last barn finally given out under the strain with nopony to raise it anew. What happened? Where did they go?

The colors bleached, the ponies gone, the Harmony and love that once sustained the land dried up and blown away like so much dust.

Except...

After countless efforts, Celestia and Luna have been pushed into a deal from a foreign leader. Trial by combat, each leader chooses a champion to fight to the death. Should Celestia and Luna win the land across the sea will cease their invasion attempts, should they win half of Equestria will be theirs.

This story was inspired and created for the "The Luna (is BEST pone) Contest.". The prompt I used was Luna, the combatant.

Princess Luna is supposed to be her sister's equal. She watches over 12 of every 24 hours, after all. But she isn't, and everybody knows it. Equestria adores the one who brings warm, sunny days, and ponies sleep through her nights. Even her sister sometimes seems to forget that she's supposed to be one of Equestria's ruling diarchs.

Luna seeks help from the only pony she thinks can make a difference: Star Swirl the Bearded. He provides a spell, one she can use to change herself into the pony she wants to be.

Unfortunately for her (and the rest of Equestria), things don't go quite as expected.

Updates Wednesdays, though it may update a little quicker at first as the Fimfiction version of this story catches up to the one posted on Patreon. Cover by Zutcha, as always. These just keep getting better, don't they?

This is a Patreon-sponsored story, written for Aurora Gleam. So tremendous thanks to them for making this adventure possible.
