Summary
Byleth has lived most her life inside of the monastery's walls with Jeralt, Sitri, and her younger brother Belial. The monastery is overseen by her grandmother the Archbishop Rhea. Most people would say that Fódlan is at peace.
When a plot to attack the heirs of the continent's most powerful families is spoiled it sets into motion a chain of events that could see the crossing of two ancient bloodlines and the destruction of a thousand years of precedent.
In a world where Byleth grew up with her mother and Rhea had a real family around her what would change?
If Dimitri confessed his love for Edelgard what would come of them? What would it mean for the Flame Emperor and her quest for revolution?
And what would it mean for Fódlan?

Summary
“Fuck it,” Felix mutters, tossing his own sword aside and grabbing Byleth aggressively; one hand on his cheek, the other fisting the hair on the back of his head. The last thing Felix sees before he crashes their lips together is the widening of Byleth’s eyes, and then they’re kissing.
Felix is kissing Byleth and Byleth is kissing him back.

Summary
“What do you want to do?” Byleth asks once they're sure the class is out of earshot. His eyes are understanding; sympathetic but not pitying. Sylvain brings their foreheads together, closing his eyes, just appreciating Byleth for a moment.
“Distract me,” he murmurs, ducking down and pressing his lips to Byleth to indicate what type of distraction he’s in the mood for.
He wants touch, pleasure, the inability to think through a haze of lust.
Miklan is dead. Sylvain wants to be distracted, and he wants Byleth, who he met a year before starting at the Officer's Academy, to be the one to distract him.
Byleth says yes.

Dimitri and Edelgard's secret relationship has resulted in a child. With most of Fódlan under the control of people they once called friends it seems the land might be on the cusp of a sustained peace. At the Millennium Festival the class of 1181 reunites for the first time since their hectic year together.
Almost like nothing ever changed the kidnappings and attacks at the school begin anew and the mysteries that threatened the lives of Byleth's Black Eagle class now threaten to tear all of Fódlan apart.

Summary
"When she looks up again Edelgard has vanished into one of the countless restaurant, bar and lounge hybrids that litter the city. Just upscale, meant for the type of people Byleth usually liked to stay a ten foot pole and change away from.
Usually. It unfortunately wasn't an option this time and as under-dressed as she was she knew she was about to stick out like a sore thumb, but in she went anyway. In all her leather jacket, band t-shirt, torn jeans, boots and ball-cap glory"

Summary
It’s raining. Byleth looks around. She notices hundreds – no, thousands – of soldiers clashing on a battlefield. Barely audible over the deafening combination of hoofbeats and shouts and metal against metal is a whoosh. A bright light strikes the plains, seemingly from the heavens. A blast wave knocks her over, ears ringing and the world spinning. The smell of burning flesh accosts her nostrils, and she opens her eyes to a man with golden eyes and a glowing sword.
A retelling of Golden Deer with a focus on Claude and Byleth's relationship.

Summary
Hi I'm a high fantasy author and I have some opinions about Fire Emblem Three Houses.
I'm a sucker for fluffy things, and fluffy stories, and the thought of dragons everywhere so this really seems to be the perfect fandom for that huh. A lot of these short stories will be with female byleth, but other pairs might pop up. I am simply letting myself write to prepare for NaNoWriMo (National Novel Writing Month). I don't know when these will be updated, but I will also let you know that these are not spoiler free! Most of these will be at the end of the Blue Lions route.
I hope you all enjoy!
(For those wondering, the angsty Claude/Byleth war piece was taken out and replaced with a fluff fic about Ashe. The claude fic will be posted separately on my page. Title and tags have been changed accordingly.)
