Summary
A chance encounter between Jeralt Eisner and Tiana von Riegan at a nameless crossroad in Leicester changes the fate of Fódlan and beyond when Tiana convinces Jeralt to join her in traveling east. Their children grow up together in the Almyran court, companions and friends despite the machinations surrounding them.
The cosmos of her heart swirls into colors unknown, and she’s vaguely aware of how the physical affects the movement of the stars. It’s all out of order, and yet she can’t be bothered to arrange it the way the physical world does. A woman cradles her. Her body rocks in time with wheels. A boy with blood unattached to any other threads of life whispers under his breath. A star who has forgotten how to be one pours light into her. A man with threads of stardust thrumming under his skin pulls her from a river.
Then, something shines, brighter than the rest; it comes from the heartbeat she’s taken in lieu of her lack, the one she first learned before he had even left the womb. Undistilled love, taking physical form in a stolen kiss, tears that are not her own on her cheeks. It falls right to the center of the nebula, the brightest light in this heart of a star.

Summary
“Romance novels don’t really go into detail about the difficulties of raising a child,” Edelgard said, because apparently it fell to her to be the intelligent one here. “Just so you’re aware.”
“Oh no, I am aware,” Byleth said. “The book was just only what got me thinking and… well, that’s when Sothis and I got to talking about it…”
-----
Sothis schemes, and the Hegemon and her former teacher try to embark on the next chapter of their lives together. Hubert just wishes that Edelgard hadn't come to him for advice! He cut down her enemies, not gave parental advice.

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
"The idea of time travel is a petty thing, because no matter what you do the universe will always punish you in the end."
He remembered saying that to one of his students when they joked of the concept, it was more out of instinct than anything. He wasn't wrong though, after all the vivid images of seeing your loved ones dying as if on loop had to be punishment.
Maybe the many failures is why he was here, in a ruined city where buildings scrapped the sky. Monsters teeming in air, sea, and land where he was nothing more than an entertaining figure to a God's will.
'Constellation,' he mentally corrected himself, 'Edelgard would hate it here.'

Summary
The final battle between Shez and Byleth goes horribly wrong, with a climactic clash between the two avatars of the gods. Byleth’s Divine Pulse misfired, flinging her consciousness way back in time along with reawakening Sothis. Now the course of history has been shifted, with many names and many faces being the same but equally different… can Byleth crawl her way to her golden route or will she be left trying to save fragile lives of students that are no longer her own…
Basically, this is a roleswap fic, where I thoroughly scrambled all of the cast in three houses to give different backstories, skillsets, and interactions between the characters you all know and love.

Summary
After having lived the same life, and having fought the same war, over and over and over, Byleth has had enough.
He has seen every possible ending. Reached every possible conclusion. But surely, there has to be an ending where everyone is satisfied.
And so he tries again, and again, and again. With Sothis' power, they should be able to find it eventually. And with the knowledge of four separate lifetimes guiding their every move...
You'd think they'd be a lot better at this.
