    Summary

    Seteth had thought his Alpha urges dead after centuries without being around an Omega other than Flayn. He quickly comes to realize that was not the case when he meets Byleth, the only human Omega he has ever met.

    This is a retelling of Fire Emblem: Three Houses from the point of view of Seteth, and an ABO fic. I'll be weaving in things from all three routes, though the initial frame of the fic will be Azure Moon, it will continue past the end of that route and have events from the others. Assume massive spoilers for everything FE3H.

    Summary

    On the rare occasion they get close enough for him to scent her, the wave of nothingness that he gets every time acts as both relief and a reminder for him to stay on his path.

    Summary

    Between accepting a teaching position, the death of a father, betrayal, a five year long slumber and a war, it never seems a good time for Professor Byleth Eisner to take a moment. Regrettably, this does come back to haunt them. As soon as the war is over in fact. After masquerading so long as a beta for both convenience and safety's sake and successfully suppressing their heats, Byleth's body gives a not so gentle bid for attention concerning their second gender. At a really bad time.

    Summary

    Byleth presented as an Omega at an early age. Jeralt took good care of her, taught her how to fight, and made sure other Alphas stayed away from her. Things are different at the monastery, though. There are no other Omegas that she knows of; only Betas and Alphas. This story is more so wrapped around Claude and Byleth's relationship, and hiding it from the higher-ups. Two-Chapter updates every Tuesday and Friday!

    Summary

    Byleth is here to change the future goddamnit, his new omega status be damned.

    Or:

    Byleth gets involuntarily thrown to the past by Sothis with a new body. A clearly omegan body which is strange since Byleth was pretty sure that he was an Alpha before all of this.

    Oh, and his father doesn't know him.

    Summary

    "The Ashen Demon, possibly the most deadly omega in all of Fodlan. I suppose it is a fitting title for someone on the gray area of the land of the living and dead. Tell me mortal, how can you be so sure you are not a ghost?"

    Many wish to turn back the hands of time - to relive another day, or to fix a mistake made only moments earlier. Yet, for Byleth, it seems more of a curse than a blessing. Every choice has a consequence. All he wants is for his loved ones to be safe, but even that can seem too much at times.
