Summary
What if Sitri never died, and Byleth was raised at Garreg Mach? What if Seteth was the one who Rhea decided to hire as a professor? And what if Byleth didn’t trust Seteth at all? (In other words: this is an AU where Byleth and Seteth switch places, yet still manage to fall in love.)
FINISHED!

Summary
“Seteth, come sit for a minute. Sit, sit.” The man topped off Seteth’s untouched cup in his hand, causing liquid to spill out.
“…Thank you,” Seteth said, unsure of what else to say.
“Now, you are family,” the man wheezed. The alcohol on his breath was far stronger than the beer from the keg. “All of my life…I’ve had a lump at the back of my neck, right here...”A just-for-fun FE3H x My Big Fat Greek Wedding crossover where Byleth introduces her fiancé to Jeralt's Mercenaries.

Summary
What if Byleth transformed immediately after receiving Sitri's crest stone when she was born, and she was raised by Rhea instead of Jeralt? What if Seteth didn't come to Garreg Mach until after Flayn woke up? What if Jeralt was the new professor? Oh — and what if Byleth and Seteth were forced to get married at the beginning of the story?
An AU longfic about a fledgling goddess and a lonely saint.

Summary
What if Byleth was a UFC fighter, and Seteth was her new trainer?
(In other words, my eyes were opened to the glorious possibilities of a UFC AU fic and I have not known peace since)

Summary
"That's a lot of power for one person to hold," Byleth observed.
Seteth nodded. "It is," he said. "Just as the archbishop's followers look to her for guidance, so will your students look to you."
Byleth is many things, least of all a natural-born leader.

Summary
Her eyes are wide and eager. "Miss Varley…" he says reluctantly, silent for a beat as he finds the will to press on, "there is something we need to discuss."
The mood change is immediate and palpable. "Oh," Bernadetta says, sitting up a little straighter, face falling into worry. "Is there — I mean, have I done something wrong? I'm sorry, I know I talk too much, I just get so excited…".
Seteth has a difficult conversation with Bernadetta about feelings.
