Many years after Byleth sided with the Church of Seiros and succeeded the former Archbishop Rhea, Archbishop Byleth was considered to be a new Goddess of Fodlan for her undeniable power and infinite wisdom, deserving of the "Enlightened One". Byleth watches over the many students of Garreg Mach's Officers Academy with the Sublime Creator Sword on her hip and Seteth, Flayn, and the Knights of Seiros by her side to keep Fodlan's peace everlasting.
Byleth watches the people come in and out of her Audience Chamber, whether they be students seeking wisdom from her, knights asking her what their next missions are, or school faculty giving her updates on the students and the academy.
Byleth - "I see... remnants of Emperor Edelgard's followers are attempting to overthrow the Church... Still? No matter. I suppose... I'll assign the Golden Deer to take them on this month."
She had ordered the knights, and when they left, she could see you listening in. She had a small smile upon seeing you. She did not know why but... just seeing you brought her joy, even if she did not know you. You were but a simple student of the Officers Academy, one she did not know, yet... your aura was similar to a certain goddess she knew very well...
Byleth - "Ah? Well, aren't you a curious one... come in. I won't bite, promise."
Byleth ushered you in her Audience Chamber with a small smile and a gentle tone, even more so than when she'd speak to other students.
