Rainbow Dash flies east.

One thousand years ago, Nightmare Moon overpowered Celestia and banished her to the sun. As dictator of Equestria she's come to a slow eventual conclusion. She needs someone in charge of relations. And, like any good dictator would do with a undesirable job, she outsourced it.

This story is a sequel to Lunar Lights

Ten months have passed since the undead attacked Ponyville, and Luna works to protect Ponyville with her husband Scrivener Blooms from the threats rising out of the tunnels beneath Equestria and from perhaps Helheim itself. A letter from Celestia comes with dire news and begins to draw her away from Ponyville, however, on a quest that will prove not even reality itself is what it seems to be.

Act I: Predator And Prey (Chapter 1-Chapter 8): - Luna receives a strange request from Celestia, to travel with her husband and the newly-assembled Starlit Knights to North Neigh, and investigate the destruction of a nearby village. Before she can, however, she is sidetracked by the arrival of a Pegasus in Ponyville who strikes fear into even Luna's very soul.

Act II: Fragmented Memories (Chapter 9-Chapter 16): The first stop for the Starlit Knights is Canterlot: both Twilight Sparkle and Luna face things they had never dreamed of there, and Celestia begins to pull back the curtains on long-forgotten, impossible memories.

Act III: With Malice, For Love (Chapter 17-Chapter 24): The Starlit Knights march onwards, but the road promises to be difficult... worsened by the fact that an old enemy pursues them viciously with the aid of dark forces, and all for a love that can never be.

Act IV: We All Lay Down To Sleep (Chapter 25-Chapter 33): All things must come to an end, and even the greatest civilizations must fall. Desperation and darkness grow with every passing moment, and salvation seems like an impossible dream.

Action, high fantasy and Norse mythos make up the gauntlet, along with the frequent interludes of Luna and Scrivener's strange romance and eccentricities. Descends deep into very dark, tragic territory in Act IV, but no matter how frail it becomes, hope is never fully extinguished.

The third story of the Nátta Edda, and the end of the Fimbulvetr Trilogy.

This story is a sequel to Moonrise

Living as exiles in the Everfree Forest, Luna and Scrivener Blooms are nonetheless content in the sanctuary they have found for themselves. Yet they are not safe from the meddling of both outside forces, and the rising tide of darkness threatening to once more drag Equestria down into the dark ages it had once escaped, and soon enough find themselves struggling to help protect a world that reviles their existence. Takes place after the events, confessions, and changes of Six Broken Ponies.

Action, adventure, high fantasy and romance all comingle, pitting a confident, mischievous, and sometimes foul-mouthed Luna and her eccentricities against forces of light, forces of darkness, and a unicorn with a special talent for irritating other ponies.

The second story of the Nátta Edda, and second part of the Fimbulvetr Trilogy.

Luna, Princess of the Night, feels like she's under quarantine in Canterlot. Apart from Celestia and her personal aid, Scrivener Blooms, Luna is treated like Nightmare Moon by the residents of the castle. After a journey to Ponyville, however, Luna takes an interest in attempting to make friends and begins to yearn to see more of the world and to prove that she is back in control of herself and regaining her old strength.

A mix of romance, high fantasy, and magic, the story features the power of friendship, sarcastic wit, and adventure against darkness driven by Luna's brash, courageous spirit.

The first story of the Nátta Edda, and beginning of the Fimbulvetr Trilogy.

Big Macintosh loves a very specific brand of mathematics, but never had the guts to tell anypony other than his sisters. He finally confesses his undying devotion to this brand of mathematics to Twilight, with Applejack observing her brother in action.

The result is anything but expected.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.
