Byleth's Sorrow

In his first life, Byleth joined the Golden Deer house, and watched as Nemesis slaughtered his students. In his second, he joined the Blue Lion house, and watched his king slowly fall into insanity. In his third, he tried to convince Edelgard to stop the war, but could do nothing to stop her as she killed the Immaculate One. After reseting one last time, Byleth, broken, hides himself deep in Abyss.
