I: The Adoption and The Mock Battle

Rodrigue adopts Byleth and renames her Byleth Rose Fraldarius before she meets her older brother Glenn and their uncle the morning after Rhea leaves her in a basket on his doorstep and knocks on his door before she leaves at night in early November 1159. Nearly 20 and a half years later, in March 1180, Byleth and her younger brother, Felix Hugo Fraldarius, attend the officers academy alongside their friends. 4 years ago, she saved their older brother Glenn and Dimitri's father Lambert from getting murdered by sinister mages and helped Dimitri save Dedue from the mages as well.
