Nintendo confirmed that the saved data for Cindered Shadows in Fire Emblem: Three Houses Expansion Pass Wave 4 DLC is different from the main game. However, progress in the side story will influence what you can do in the main game, including exploring Abyss. By continuing to improve on Cindered Shadows, players can interact and recapture the four Ashen Wolves in Part 1 of the main game. Once they have joined your house, they will be available to participate in battles and divisions. You can check out some new screenshots showing Cindered Shadows in the gallery below:
