In a realm ruled by Princess Celestia and Princess Luna, two brothers find themselves torn asunder by a burgeoning royal conflict. As the kingdom's tranquility fractures, the siblings are propelled onto opposing sides, compelled by duty, loyalty, and conflicting ideals. Amidst political upheaval and the looming threat of war, their unbreakable bond is tested, and they must navigate treacherous waters of betrayal, sacrifice, and the haunting presence of an imminent darkness. Set against the backdrop of a kingdom on the brink, this tale unravels the intricate threads of kinship and power through the brother's letters to each other, shedding light on the events that unfolded before Princess Luna's imprisonment, forever altering the course of their world.

Inspiration

After the events with Twivine, a very special girl is coming back for revenge on Fractured Loyalty aka Rainbow Dash. This does not go well for our heroes for this friendship is going to be tested.

Twivine is locked up in a prison cell when one of the Dazzlings Adaigo decide to let her roam free, it's up to Fractured Loyalty and her new partner Alex Night to stop her from destroying the city and possibly the world

Dear Princess Luna,
I am beyond honored that you have chosen I, your most humbled subject, as your student and assistant. I shall strive to show you my worth as one of yours, and look forward to working under your wing.
Your Ever Faithful Acolyte,
Sable Light

Sable Light serves her country, but mostly her beloved princess, Luna. Come bat infestations, racial disputes, threats from aggressive Griffon imperialists, and other problems challenging the kingdom's success, Sable stands firm in her faith of her kingdom's rulers. Until, as the land reaches a boiling point, a civil war renders Equestria into fractured shards of harmony long believed unbreakable. As the moon eclipses the sun, the former apprentice faces a crucible that questions unity against liberation, good and evil against the absence of both, and whether her actions will reveal a betrayal or loyalty not only to her kingdom but those she loved the most.

Heads up, this'll probably be a long buildup.

Art by yours truly.

Note: I'm in unfortunate and terrible need of an editor, or a few volunteers to lend a careful eye. If anyone is willing to scout through future (as well as current) chapters for grammatical and spelling mistakes, that would be awesome! I'll link you the most updated Google Doc draft, or share a super secret password for Unpublished View chapters
