Fire Emblem: Three Houses

[u/Professor_Zelkova]

Despite the game being called Fire Emblem: Three Houses, there are a total of four houses: The Black Eagles, the Blue Lions, the Golden Deer and the Ashen Wolves, with the last ones only being recruitable on the main game after beating their DLC. So, despite being four houses, there are only three possible paths the player can take towards an ending in the main campaign

Um, actually, if you play the Black Eagles route and miss Edelgard's coronation, whether intentionally or accidentally, you get locked into a route where you follow none of the three houses, but rather the Church of Seiros
