Was it a shock in that first cutscene when the protagonist of Fire Emblem: Three Houses shows up as the antagonist of Fire Emblem Warriors: Three Hopes? It’s just the kind of twist we’ve come to expect from the series. However, it doesn’t have to end with one of you impaled on an enchanted sword. You can be friends instead. Byleth is available to be recruited into the ranks of your army. As is the Patriarch of Puns, Alois, and Super-dad, Jeralt. Not only that, Byleth is one of the most powerful characters you can have at your side. Plus, having them in your party puts you on the path to a much happier ending.
Each faction has a different way of recruiting the Ashen Demon, and it’s possible to blow your chances on each one. You’ll be warned in advance, so don’t forget to make additional saves as needed.
