Summary
It can be difficult serving as a teacher at the prestigious Officers’ Academy.
Tutoring the cream of the crop of the Empire, the Kingdom, and the Alliance carries a lot of expectations.
And trying to keep order amongst such rowdy students, nobles and commoners alike, can be a labor all on its own.
Fortunately for Byleth, he knows exactly how to keep his male students in line.
All it takes is patience, a sturdy chair, some rope, and a firm hand.

Summary
Yuri meets Adhara, former caretaker regent of the Abyss in his words and Byleth. It never hurts to have a quick chat or two with one of the Cardinals of the Central Church, a selective group otherwise secretive to a fault or so they say. But he has his ways of getting under a person's skin.

Summary
An alternate take on canon to give Edelgard the story she deserved and the house leaders the friendship they should've had with a heavy, HEAVY emphasis on Yurileth. It starts with Azure Moon, but adds in Verdant Wind's and Silver Snow's unique chapters while also yoinking lore from Crimson Flower and a dash of Cindered Shadows before mixing on high for sixty years.
There's a tiny bit of Three Hopes, but only really adding Shez, Arval, Epimenides, Holst, and (actual) Monica to the main plot of Three Houses.
Hopefully that'll draw your attention enough to give it a try? Idk. More notes in the fic because I only get like, 1k for a summary.
EDIT: I also just noticed that I tagged this thing with 'starts Azure Gleam' instead of 'Azure Moon,' but editing tags is a hassle. I promise I mean Azure Moon, lol.

Summary
“Aah, I could die here and now”.
As soon as that thought came, she inadvertently whispered it out loud. The little girl thought that nobody could hear her, but in reality she caught the attention of two young twins, who were a little more older than the pitch black haired girl from the alley. Under the fallen snow, in that afternoon of the first day of the Ethereal Moon, the girl had a fated encounter.
___
Dying on Christmas' day for playing a videogame too much, Balan Eisner took it with optimism. After she understood of being in the world of the last videogame she played before her death, her adoption in the Eisner's family gave her a dream to absolutely realize: to bring a new dawn on Fodlan. Balan would have done anything to avoid certain massacres or heartbreaking events, even sacrificing her own sanity or killing her past morality. -

Summary
It was supposed to be a simple mission. Byleth thought it would be a nice break for his students after their recent victory. He hadn’t anticipated putting his students in danger and he was blindsided by the looming shadow of his house leader’s past. A part of him wished to forget it, but with lives on the line, Byleth knew better than to ignore the potential threat this information presented.
Claude couldn’t stop berating himself. How could he let down his guard? Teach had heard everything. His classmates were witnesses and would demand answers. But there was no way to spin the news that one of his older siblings had hunted him down and wouldn’t rest until they cleaved his head from his shoulders. And with his injuries all he could do was lay in bed, drowning in his panic and dread, all while he smiled and did his best to reassure his boyfriend all was well.
Or
I'm still mad that we only got crumbs of Claude’s backstory in Three Houses. After seeing Warriors Three Hopes debut trailer I took a crack at a side story that could have been used in the main game to help give more to Claude’s backstory in Alymara. Some good old angst and soft Dimiclaude vibes.

Summary
Byleth Eisner, for his entire life, has had great difficulty understanding what emotions are like, but he knew one thing for sure: he felt like an outcast, a freak. Between his ability to speak to animals like it's the most natural thing in the world, to being known as the Ashen Demon who kills his enemies ruthlessly and efficiently, those around him both hate and fear him. Lonely and not understanding why, he takes it as normal until a fateful encounter with a sky-blue-haired girl named Marianne, who reminds him of a friend he knew from childhood.
Marianne, for her whole life, had felt like a curse and a burden to others. Her greatest fear was her crest and becoming the very thing that she had always feared her ancestor became. Feeling like a curse and a burden, she holds people at arm's length, afraid to befriend anyone, feeling like an outcast and having nowhere to belong. Her only solace is with animals. Not even her childhood friend is able to save her from the loneliness she feels. Things change when she meets the professor of the Black Eagles, who reminds her of her friend Byl from her childhood.
