A kingdom needs a protector to defend it.
A protector needs a weapon to defend the kingdom.
A fundamental truth from the times where Luna was the hero of Equestria instead of a nightmarish fairy tail.
So now that Luna has finally returned, she is in need of a new weapon to protect the kingdom once more.

But when swinging a sword becomes a major obstacle for the princess, is it the fault of the blade, or the one who wields it?

Two weeks before the 1000th Summer Sun Celebration, Moondancer discovers a forgotten spell scrawled across the pages of an ancient book. Casting it threatens to turns her world upside down: faced with glimpses of an Equestria contradicted by historians, she must use all of her intellect to piece together the mystery surrounding Mage Meadowbrook, Princess Celestia, and the mare with the mane of stars—before the project destroys everything she's worked for.

It's a good thing she can rely on Twilight Sparkle for help.

Spanish Translation from Spaniard Kiwi!

Training Session
We all knew Twilight Sparkle was a powerful sorceress, but none of us had ever realised just how powerful she truly was. It is no underestimation if somepony said that she’d be able to challenge an immortal to a battle and come out as the victor. The possibility was there, of that there was no doubt, the only thing that was needed for her to actually defeat an immortal, such as myself, was for her to realise her full potential, for her to realise just how much power was stored in that small body of hers

Luna and Twilight are sunk into a fractured, feudal world, where the knowledge of magic is lost. Penniless and depleted, they're forced into playing by other ponies' rules, all the while trying to discover even where home is.

This story is a sequel to Inexcusable

She looked just like Princess Celestia, except marred and broken. Her ceremonial barding had rusted slightly, and dirt matted her coat. Most noticeable was her hair; black streaks accompanied its usual multicolored luster. They looked like discolorations in an old photograph.

Worst was the scar across her chest. Her armor covered it, but nothing could hide what it meant.

The tarnished Celestia smiled at Luna. "H-hello, monster. I would say I am glad to see you, but that w-w-wouldn’t be quite accurate."

Celestia has always been more interested in the future than the past. She does not dwell on mistakes – hers, or others'.

But sometimes memories lurk in the oddest of places, and when they strike not even a god can resist their gravity.

A short story written for the recent Writeoff competition.

Luna struggles with the edges of sanity and feelings of depression after her time of lunar isolation.

Based on Equestria at War mod.
After the Equestrian frontline had collapsed against the Changeling army in the Coltfoalnian Campaign and the Breakthrough at Mariposa. The remnant of the Equestrian Royal Armed Forces(ERAF) abandoned Northwestern Equestria to defend the vital region of Central Equestria.

An earth pony was drafted into ERAF and was assigned to the newly formed 3rd Canterlot Garrison with the obvious task to defend the Jewel of Equestria, Canterlot.

Unbeknownst to him, he will witness and experience the largest battle in the war.

Equestria has not always been the peaceful land it is known as today. In the days of old, ancient beings wandered its lands, all seeking to assert their power over one another. Some sought power, others sought a challenge, even more simply wanted to cause misery in others for the simple thrill of it. Very few and far inbetween were kind, or forgiving, as they were usually the first to perish.

Enter a young mare by the name of Celestia, and her sister Luna. With their parents dead, the two siblings suddenly find themselves in a position of power they are ill prepared for. However, they must rise to the occasion, or their subjects and their kingdom will be crushed underfoot by the monsters that seek to devour them all.

Join these siblings, and experience the pain, struggle, battles, and hardships they both had to endure to make Equestria into the kingdom it is today.

When Twilight finds herself urgently summoned to Canterlot by Princess Celestia, she knows something's terribly wrong. She's faced enemies far beyond her years but nothing could have prepared her for this. The skies have turned against the royal sisters. The sun and the moon have rebelled.

While racing to find the reason behind this, Twilight discovers more than she could have ever imagined...the story of Celestia's past, the ancient battles that have never truly ended...a darkness beyond all knowing that lies just beyond Equestria's borders.

As centuries-old secrets come to light, Twilight realizes that her new status as princess has bestowed upon her much more than just wings and a crown. Yet with each step closer to an answer, more questions arise. Why has Celestia barricaded herself inside the castle? Where does Luna keep disappearing to in the middle of the night?
