After the war for Fodlan, Byleth and Jeritza threw themselves fully into Emperor Edelgard's struggle against those who slither in the dark. Though the battle proved vicious, none could stand against the combined might of shining sword and reaper's scythe, and the pair became venerated by history as heroes of Adrestia. Once those who slither in the dark were forever vanquished, the two heroes stole away in secret and vanished without a trace. Their whereabouts thereafter have been the subject of much conjecture among historians.
