The Eagle's Flight

In the Imperial Year 1180 in early April (Great Tree Moon), the player character, their twin, and their father, Jeralt, camp in Remire Village when they are attacked by Kodlak and his bandits. Fighting alongside three young nobles, they manage to defend the village. During the battle, the player character (only if Byleth or Beylen) attempts to save a white-haired noble but is mortally wounded. In that moment, time suddenly stops, and they meet a mysterious green-haired child from their dreams, who scolds them for their recklessness and reveals they were the one who froze time. When time rewinds, the player character successfully saves the noble and defeats Kodlak. After the battle, Alois and the Church of Seiros arrive, recognizing Jeralt as a former knight and inviting the group to Garreg Mach Monastery. On the journey, the player speaks with their twin, confiding in them about the strange experience, only to learn that their sibling has had a similar one before.
