Summary
What if Jeralt were a main character? What if he was the professor instead of Byleth? What if Byleth had the chance to play student, and got to be a young and socially awkward adult instead of being thrust into the 'Professor' role? What if Jeralt (very reluctantly) adopted each of the Blue Lions?
These are just some of the themes that will be explored in this fic. Papa Jeralt is doing his best. Claude is kind of a jerk in the beginning, but slowly starts to open up to others. Yuri has lived the entirety of his life going from impossible situation to impossible situation, and has the trust issues to match.
Oh! And Byleth and Felix get to be sword bros.
Tagged relationships are endgame, but there will be several twists and turns along the way. OT3 is primary ship, but Sylvix is highlighted throughout the fic. Events of Cindered Shadows will be included.

When you and your friends stumble upon Abyss, a subterranean world cloaked in mystery, you cross paths with Yuri, a guarded and enigmatic student who keeps his distance.

Summary
"My dream is to introduce a world that my mother would have wanted to see. One where the blood pumping through one's veins does not determine their likelihood for leadership. One where power isn't so centralised that a single individual forces subjugation and submission on their foes without facing the consequences. A world where one's place is determined by the content of their character, not by easy opportunities born of empty courtships and swinish blood. Such a world simply cannot co-exist with the whims of a goddess. It doesn't matter where you go, you will always see beggars on the street, begging for their version of a deity to fill their empty bellies. Such gods and goddesses, however, never come. I know my vision for the future will never come true, I'm not stupid as to dream of a utopia. So I'll have to settle for the next best thing. If I force a situation in which people are forced to rise against their oppressors and take their destinies into their own hands...Then maybe, one day, I'll be able to wash the blood off of my hands. Tell me, Yuri, knowing what you know now, will you still walk with me? Will you still walk towards a world for the people? Knowing that I plunged it into darkness?"

Summary
Fate was never supposed to bring them together.
In one timeline, the Mysterious Mercenary was never born, leaving the Ashen Demon to face their choices alone. And in another, the Mysterious Mercenary and the Ashen Demon were destined to fight to the death.
However, in this timeline, Jeralt Eisner, in a remote village in Leicester, finds a purple-haired girl that his daughter, despite her oddities, could not part with, leaving him forced into taking the girl under his wing.
This simple twist will change Fódlan forever, but will this twist of fate bring this timeline to a platinum future, or to an age of ruin?
(Or, Three Houses/Hopes with Byleth and Shez as siblings amongst several other changes)

Summary
When Arval awakens, so too does Epimenides. Rather than simply wait for his opportunity, he takes a chance to subtly influence his wayward vessel—and so Shez's need for vengeance becomes all-consuming. Byleth doesn't mind the frequent fights with an interesting opponent, but her new duties as a professor sometimes clash with her desire to continue teaching her rival.
Meanwhile, Edelgard is left very confused, and Hapi is bored in a lightless pit.
My take on a Shez-in-Three-Houses story, with perspectives split between Shez, Byleth, Edelgard, and eventually Hapi—along with other characters interspersed. Part one of an eventual three-part series. This part will conclude at the beginning of the timeskip.

Summary
Fate has a way of playing tricks on people even as it brings them together. Some of Foldan's legends say that when calamity comes, the goddess binds the souls of champions to ensure they fight at each other's side, onward to victory. Less spiritually-inclined individuals say that conflict makes friends, allies and more out of strange bedfellows.
Or, in which Dimitri punches out a racist and history is changed as a result. A merging of the Blue Lions and Golden Deer storylines.

Summary
The first time Ashe learned Yuri had a mother was after they put down Aelfric. Yuri had just shrugged, stating that he'd had his reasons, and Ashe had backed off. Right then wasn't the time to bug him about the particulars of how he'd wound up underground after going to the Officers Academy, he'd just been too relieved Yuri was safe.
Five years later, they return to that dropped conversation topic, and then some.

Fate that would lead him to one day call the Ashen Demon, his beloved. (Spoilers! Currently on Ashen Wolves DLC - More Papa Jeralt and Sassy Sothis too!)

The Fourth House by Smackstar101

Summary
There had always been three houses at the illustrious Gerrag Mach Officers Academy, The Black Eagles, The Blue Lions, and The Golden Deer. However, with the increase in people and activity within the Abyss, the underground catacombs underneath the monastery, Archbishop Rhea needed a reason to justify increased surveillance of the area. Fortunately for her, a bishop named Aelfric came up with a most wonderful idea: incorporate Abyss into the Officers Academy by creating a new house for them, thereby justifying any additional resources and personnel as a way to assist Abyss, at the cost of the Church's surveillance. And thus, the fourth house, The Ashen Wolves, officially came to be.

I finally persuaded my humble collaborator that she deserves to be properly credited in this work, so better late than never! Even though the original rough idea was mine, and it was me who wrote this, she was a huge help with further ideas and many of the details throughout the fic. Thanks again to you, Monica_Edelfan1, it was fun doing this together! <3

Summary
"This world… something has changed… Your story… it is almost time to… begin…"
The Class of 1180 came from all over the world. Some were nobles in high places. Others were born in the dirt and climbed their way to the top. Still others found their home with people, no matter if they stayed in one place or traveled the continent. However, they all found their way to Garreg Mach Monastery for a year, forging lasting bonds that would make the way for a new era in Fodlan.
However, the road there is not an easy one. Between an underground organization hell-bent on destroying the world and a church driven by selfishness and greed, the Class and their allies were Fodlan's only hope at regaining peace. Love and war, peace and chaos... only one side can come out on top in this battle of determination and willpower.
Who will it be?

Helping Out Search for the Chalice by ImaginaRY_DERby

Summary
If Byleth were to be given a question of how life is currently going for them between one and ten(one is a crawl and ten is a galloping horse), they would stay silent for a bit. Then they answer with eighteen. Why? Because that's what Byleth is currently feeling like. A wyvern that clipped its wings and is falling at the speed of sound with no reins and the destination is Ailell.
At least that's how Byleth felt like ever since they grabbed the Sword of the Creator. Whispers, end of month mission planning, discussions, lesson planning, fight demonstrations, tea time with the Archbishop, meal eating with every student, and worst of all no time to fish. Now Byleth is helping these Underground kids that barely see the sun twice a week in defeating enemies and finding a... cup? Wait, chalice. Let's hope it doesn't take too long.

Summary
His isn’t the body of a prince or a duke, and he isn’t stupid enough to think it’s desirable to anyone but those looking for a pretty face and something to abuse. If Byleth is a man like that, then it would be all the easier to lose interest, to let him have his fun and then part ways without a second thought. But to see repulsion after kindness would be a worse punishment than anything Aelfric could ever dish out.
———
In the midst of their scheme to acquire the chalice, Aelfric discovers Yuri’s true feelings for the meddling professor and gives him an ultimatum.

Summary
In the Imperial Year 1180, two boys from the Holy Kingdom of Faerghus are sent to the famed Garreg Mach Monastery to learn amongst the wealthiest and most powerful people in the entire continent.
One, an ex-commoner, Ashe Duran Ubert. Born into poverty and spending his first few years watching over his siblings, Ashe was taken in by a gallant knight, Lonato. That man's actions and demeanor gave Ashe an unquenchable desire to help anyone in need and become a knight like those in his favorite tales.
The other, a Faerghus noble, Felix Hugo Fraldarius. After seeing his homeland, culture, and even his best friend for what they truly were, Felix grew cynical and battle-hungry, disillusioned with the world he lived in and estranged from almost everyone he knew.
Under the guidance of a mysterious mercenary and professor of the Black Eagles, Byleth Eisner, the young knights-in-training will be thrust into a world in chaos and on the brink of revolution. When that time comes, they will have to decide between the devil they know or fighting for an uncertain future.
A coming-of-age/action-centered story from the perspective of Ashe and Felix. Primarily on the Crimson Flower route, as well as Cindered Shadows.
