Tenth and final story in the Blooming Moon Chronicles/99 Worlds Saga.

This story is a sequel to The Age of Wings and Steel

Tyria Metrel, an ensign assigned to the Equestrian embassy in the island city of Zyre, has her hooves full dealing with pirates and bad-tempered politicians. On top of that, a new ambassador named Rye Strudel has arrived on a mission from Princess Celestia, and he might well be the strangest pony she's ever met. Ambassador Strudel is a pegacorn, one of the rare crossbreeds unable to fly or do magic, but Tyria soon learns that his disabilities don't prevent the ambassador from getting himself into deep trouble.

Rye's cheerful curiosity and drive begin to stir up feelings Tyria thought she'd given up on—when he's not making her tear her mane out in frustration. After the two of them stumble upon a treasonous plot to seize control of Zyre, they'll have to work together to foil an old enemy, save the city, and maybe even find love along the way...

... provided they don't drive each other crazy, first.

This story is a sequel to Upheaval: Breaking Point

Following the events of Breaking Point, Twilight Sparkle and her friends discover that Equestria's demise may not come from an enemy invasion, but from within. The Barrier Lands and the Heartland begin the slow and uneasy process of reuniting into a single Equestria, but this long-delayed joining is already in danger at its conception.

With Celestia's power in her grasp and her agents by her side, the wheels of Black Rose's plans for Equestria's future continue to turn. However, her brazen gamble has done more than just bring down a centuries-old barrier. Ancient powers begin to stir: the remnants of a dark period in Equestria's history, the immortal inhabitants of Celestia's homeworld, and a rising tide of darkness coming ever closer.

Three hundred years after the fall of Princess Luna, Equestria teeters on the brink of disaster. Bitter political infighting and power-hungry nobles threaten to tear the country apart in a bloody civil war, while in the south old enemies prepare to reclaim their ancient homeland from the ponies.

As Princess Celestia desperately strives to hold together her splintered nation, she sends a young pony on a quest to the northern lands that border Equestria in order to plead for aid against the threat of Grypha. This unlikely messenger is Rye Strudel, the flightless, magicless, half-breed son of a guard and a baker. Rye must do the impossible and unite the thanes of the north... for if he cannot, there may be no home to come back to.

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.

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.
