    Summary

    Byleth is tired. She's tried over and over again, unsuccessfully, to save everyone she can, but there's always something she gets wrong, something out of her control. She's gotten very good at navigating life at Garreg Mach, and time is basically meaningless to her, so she soldiers on, trying to find some way to save everyone she loves. As she readies herself for another try, Fate throws her a curve ball - a fraternal twin who was raised at Garreg Mach, unbeknownst to her or to Jeralt. She resolves herself to learn to work together with her unexpected sibling, who harbors his own suspicions and agenda. Will this, finally, be the life that goes right?

    Summary

    Sitri Eisner is gifted beyond her architect’s expectations, but even she cannot stop the river of fate. She burns bright in life and tumbles early into an unmarked grave, leaving in her wake a grieving husband and a peculiarly quiet child.

    But Sitri was born smart, so on her deathbed she does not try to hold back the river; she diverts it instead. Twenty-one years later, its currents fade to reveal a blue-haired mercenary... and her green-haired twin sister, who carry Fódlan into its future.

    Edelgard could never have seen this coming.

    (An AU in which Byleth and Sothis grow up as siblings, and take their world by storm.)

    Summary

    “I told you it would come to you,” Sothis said softly. Byleth gasped, an unfamiliar dizziness rushing through her, everything suddenly prickling and overstimulating. When the wave passed, she bent over, panting. Her entire body felt sluggish, like she had been marching several days with a heavy load. Drowsiness settled like a weight over her eyes. She wanted to lie down.
    “You cannot rest yet!” Sothis snapped. Byleth’s eyes fluttered open. Sothis floated beside her, arms crossed. “I have performed this very action thousands of times over and it has never wearied me so. You must be weak indeed.”
    Byleth glared at her.
    “Besides,” Sothis said, her tone softening as she regarded the red-stained canyon floor. “There is work yet to be done.”

    In which the Blue Lions see their first real combat at the Red Canyon.

    Summary

    Both Sothis and Byleth knew the truth. No matter how much she turned back time and tried to change things, the war was inevitable. However, Sothis knew something that Byleth did not. There was a timeline where there was no war, no death, and a bright future ahead for everybody they knew and loved.

    Everybody, except one.

    Summary

    Sothis gets a lot of things out of her time in Askr. She gets a corporeal form (multiple, in fact), and the ability to move about freely without being tethered to a Byleth all day. She gets to cut loose in battle, and even occasionally gets the chance to knock a little sense into her wayward children that have made it to this strange realm. But one thing that she hasn't gotten much of, until now, is friendship. Now that she's had a taste of it, though, she wants more.

    Her first target for friend-making? Ignatz Victor.

    Summary

    He always found comfort in the skies, and today, it seemed like the skies returned the favor. Above him was a circling black dot. To other people, it would look like a bird of prey, or perhaps a wandering wyvern. But to Claude, that increasingly large shadow was the answer to everything.

    ---

    Claude has a lot of plans. None of his plans involve an amnesiac harpy that gets injured while saving his life. He ends up uncharacteristically risking his plans in order to nurse her back to health. As the two of them spend time together, the mysteries that surround the harpy named Byleth seem to intertwine with the secrets Claude holds close to his heart. Perhaps they not only share the same blue sky, but also the same fate.

Plunged into the depths of the Sealed Forest and the once mighty walls of a crumbling monastery, Byleth must piece together the truth of Fódlan's history, keep his loved ones safe from dangers striking from every corner, and answer a vital question: what makes a monster, and what makes a man?

    Summary

    'Who- what are you?' he stammered. Sweat was gathering on his brow.

    'I..' Byleth began, before stopping herself. Was something wrong? She looked down at her hands. Her skin had broken in places, replaced with shining black scales. Surprised, Byleth lifted her hand up so her face was reflected in the metal of her gauntlet.

    Her hair was a deep, verdant green, and her ears curled up to a point. Her hand froze. Nothing like this had ever happened before. Byleth's head span. As she fell to the floor, she heard rapid footsteps and a splash as her body fell backwards into the water.

    Summary

    Ever since the rumors of a magical lamp that could grant three wishes has reached Khalid's ears, he has been in search of it. Never did he imagine that he would find it in the hands of a mysterious mercenary like Byleth. Nevertheless, he plans on taking it for himself. Of course, he'd never planned to take long enough that he'd start growing onto her. Yet it's no wonder why people say that those with grand dreams like himself will do anything to accomplish it.
