    Summary

    This is where all my requests from my tumblr page @fe3hscenarios will go! I just thought it would be nice for my fe ao3 fans to get a preview as well~

    The rating is marked as Explicit because I'm also allowing nsfw requests if anyone is interested. Not every request is rated E, however.

    If you'd like to send me an ask, please do so! I definitely love the ideas everyone has given me so far. I will try to update this as much as I can.

    You can check out my tumblr master-list post here: https://fe3hscenarios.tumblr.com/post/188779091805/masterlist

    Summary

    A slightly longer fic in which the Empire takeover happens way before Byleth actually meets her would-be students at the Officer's Academy at Garreg Mach Monastery.

    The Adrestian Empire's takeover leads would be students to either enter the new Empire's Military academy or become mercenaries for hire. Byleth was known as the Ashen Demon for many years, with Jeralt raising her for a much longer time than that. While she doesn't know who she really is and where she comes from, that doesn't stop her from being curious about the new recruits her father managed to wrangle in first.

    Sylvain followed Byleth only to realize Byleth is occupied with bigger fish she wants to fry. Seeing how the new recruits also affect the older, more hardened mercenaries also gives Sylvain the chance to some less than friendly competition. There, he learns about everyone, including himself possibly.

    Summary

    Set near the beginning of part 2, Blue Lions path. With everything quite literally crumbling around him, Sylvain falls back on what he knows; flirting. He isn't prepared for Byleth to respond favorably, or the fallout from it.

    Summary

    Sylvain finds out Byleth slept around when he was a mercenary. He can respect that. It's nice to have another ladies man around even if that means competition. But, Sylvain soon finds his assumption wrong. Byleth is more of a mans man.

    Basically, the Blue Lions find out Byleth is gay and all the guys think they maybe too.

    Summary

    Though a young Dimitri and Byleth has formed a bond of sorts during their school days as student and professor, that bond couldn’t outweight the intensity of which Felix and Byleth began to realize they were one another’s missing piece. Everyone expects the soon to be king to wed the professor as soon as he claims the throne, but the reality is that while the child of feigning light and brightness holds out his hand, the swordsman that’s been lurking within the depths of shadows and darkness has already grabbed onto hers.
    ~~~~~~
    Also where Felix and Byleth find that they are one another's missing piece that provokes new emotions and thoughts from one another.

    Literally what the title says. Four times the threesome fucked in four different ways.

    Chapters are tagged more in depth in the notes so as to not clog up the work tags with useless details :)

    Summary

    The redhead smiled that weird smile that you normally send to someone you're passing by and Byleth couldn't help but chuckle to herself, trying not to stare at his expression longer to keep from laughing out loud.

    Summary

    Sylvain and Felix are only best friends and are nothing but best friends, right?

    I mean what type of best friends would you be if you didn't make a promise to each other to not die first and instead die together. Haha

    Everyone and their mother at Garreg Mach could see how much they want to be together.

    Maybe it requires something or,,,, someone to make them realise their true feelings for each other.

    Summary

    “Am I spectacle now, too? You really do need to be brought into line.”

    Byleth stood up, tucking in their chair. They leveled with Sylvain’s eyes, meeting them with a glacial stare. They both liked the hard edges of each other in this, the edge that settled into the verdant eyes, making them seem paradoxically abysmal.

    “Would you please place your hands on my desk?”

    Summary

    They're all going to die tomorrow.

    The Kingdom may be the Goddess’s chosen, but the Empire has the Goddess, and the Goddess has chosen death for her people. What’s one saint in the face of an Emperor who fears no deity, not even the one leading her army?

    Sylvain never gets what he wants. And Sylvain doesn't want to die.

    Or: Sylvain didn't get recruited to the Black Eagles, and he knows the Professor didn't want him.
