Summary
Raised in Almyra, Saytia (Byleth) knows the cost of survival. But when an underground syndicate takes her father hostage, the lethal mercenary is forced into a gilded cage: Garreg Mach Monastery.
Publicly branded a holy saint by a possessive Archbishop, Saytia must privately operate as a blackmailed spy to keep her father alive. Between the Church's suffocating dogma, a future Emperor's secret revolution, and a terrifying power to rewind time, she must find her own path before the ticking clock runs out.
Some icons are born to be worshipped; the Ashen Demon was born to burn the heavens down.

Summary
The Multiverse is an interesting thing. Infinite worlds, infinite possibilities. Some worlds may have floating blocks with coins inside, some may have dangerous aliens roaming space, others may have magical sword fighters as the norm, and the list goes on.
But one day, weird portals and weirder drones started appearing across most, if not, all of the worlds, causing chaos and dragging people into different realities. Can a ragtag group of characters who are almost entirely different from each other save the day and the ENTIRE MULTIVERSE from these enigmatic beings with unknown motivations, or will all of existence come to an end?
But uhh…seems the cast is a little different than expected.

Byleth has been the emotionless Ashen Demon for most of her life, hunting down inhumans like werewolves and shapeshifters, until her father is killed in battle and she is captured by her vampire grandmother. She is forced to lose her human half and become a vampire, where she is married off to the king of the werewolves she used to hunt. She can't kill him, can't kill herself, and he obviously hates her.
How else can she spend her immortal life, besides trying to seduce the cold werewolf king until he admits he's attracted to her? It's not like she could end up becoming attracted to him in the process... Right?

Summary
When Jeralt told Byleth to not trust Rhea, she took that sentiment to heart. Being thrust into this position, this school, these assignments, and uncovering truths and lies, She doesn’t know who to trust behind the monastery walls.
While impulsively choosing the golden deer to lead was a choice she grew to accept, Claude’s playful and tactic antics leave her with no outlets to express her grievances, or if she should trust his ploys and advances.
Sneaking out nightly serves as her only solace to deal with stresses and cope with her new life. However, when a certain boy with peculiar Ember eyes and midnight blue hair crosses her path… will she find the oasis of comfort she so desperately needs in the wake of secrets and war coming to light?

Summary
Edelgard and Hubert could fill a library with reasons not to trust others, but Byleth has never felt betrayal. Before she met them, she had never felt much of anything. Now, the professor's earnest attempts to master her new emotions more often than not seem to bait the suspicious pair out from behind their walls, making them long for another way than the lonely path they've set.
--
An emotional, scheme-filled, canon-divergent AU told from Byleth, Hubert, and Edelgard's perspectives, with a healthy side of Golden Deer crossover. Modified slow burn with lots of trust building, secret sharing, and angst.

Did this instead of sleeping. Got this idea at one in the morning. It’s now almost 3 am tho.
A smutty Zeus x Percy except… huh? What is this? Percy is top and Zeus is bottom.
Or…
I wrote this at 2 am on a weekend with my brother at a shooting competition, so sorry if it isn’t good. It is also my first time writing smut but I have read a lot of smut and made a lot of questionable Chai and Character Ai chats so I do have some experience.

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?

Summary
Please be aware there is Self-harm depicted, based on my own experiences with it and going to therapy. There is no more than scratching and blood, but please read with caution.
Also, this is based on the final chapter of the Golden Deer route in FE3H. So major plot spoilers.
~~
Her muscle memory marched her out to the wyvern stables. Unlike the timid horses that were camped closely to the grand entrance hall of Garreg Mach, the larger and rowdier wyverns were nestled in a large barn just down the slope. The mini valley was freckled with patches of lush vegetation and tall trees. A stream danced across the rocks to the ground below, the cathedrals were crying from above. Byleth’s feet flowed across the knarled roots that littered the worn path, headed toward a gurgling creek where many a scheme bubbled to life.The tips of her boots hung ever so carelessly over the eroded muddy edge. She proceeded to kneel down to hug her knees, looking at the warbled form of herself in the waters below.
She began to bawl.

Byleth learns the truth about why Rhea is so obsessed with her. Claude desperately tries to help comfort her.

Summary
During the Red Wolf Moon, Byleth falls ill prior to their excursion to Remire Village.
What initially seems like common illness turns out to be far more complicated. A mortal body was never meant to contain the goddess’s power; much less the goddess herself.
Slowly, Sothis begins to remember who she is, and understand what is happening. It seemed Rhea’s plan to revive her mother would come to fruition after all.
And Sothis vows to stop it. She will change her fate, Byleth's, and the future of Fódlan in the process.
Or, the progenitor god reincarnates—at the vessel’s sacrifice.

Summary
Blaiddyd wished now that he had taken Lycaon in after that first battle, forty years ago. Simply refused to allow Seiros and Wilhelm to take him back. He could have raised him better. He could have prevented this. Could have let Lycaon live out his days in relative happiness, free of the guilt and fear that plagued his every move as it was. A happier, healthier Lycaon would have been able to end the war.
