During the war and after.
Oliver, my original character for FE:A. I imagined him as Stahl’s son with Cordelia 😁 He would be Severa’s much younger brother who arrived in the past much earlier than even Laurent and ends up catching up to just short of Lucina’s age. Making him practically unrecognizeable to even his sister. He’s very affectionate. He also idolizes both his parents 😊
