Long ago, a terrible monster known as Ninetails unleashed a reign of destruction upon a distant land before being defeated by holy priests. While helping the land recover and purifying monsters, a fox they had in their care spawned a second tail. Despite knowing the risks, the priests believed she could be a force for good and began to train her in the ways of healing and purification. 

However, not long after gaining her third tail, word of her existence began to spread, causing her caretakers to fear for her life. They decided to send her to a distant land, a land of peace, harmony, and friendship. There, Princess Celestia found her and, interested in her ability to purify monsters, took the three-tailed fox in with the hopes she could save her fallen sister.

"Will she find acceptance and happiness among ponies? Will she save Luna? One thing is certain, her race's heritage and instincts won’t make it easy."

This story starts 50 years before Nightmare Moon Return. Humans make appearance only in prologue and they do not play any significant role later in the story. This is not pokemon in Equestria, main character is a Kitsune. Warning, bleeding, religious themes and fluff is to be expected.

In the 31st Century, humankind has spread to thousands of planets in the Inner Sphere. Once united under the glorious banner of the Star League, the Successor States and their noble houses now fight bitter wars over the scraps of empire. When a JumpShip carrying a special task force from the Federated Suns suffers a catastrophic misjump, the occupants find themselves stranded above a strange, beautiful world at once alien and eerily familiar.

Meanwhile, in the peaceful realm of Equestria, Ponyville’s resident bookworm , Twilight Sparkle, has stumbled upon hints of a secret buried for centuries. A secret that may lay bare long-forgotten aspects of Pony history and culture.

Our story begins on the planet Valexa, where the beleaguered Militia has launched a last-ditch effort to call for help against overwhelming odds.

Written with those who are not familiar with the BattleTech/MechWarrior universe in mind.
