Yhwach is the emperor of the Wandereich and the first Quincy to ever roam the land. He is the spawn of the Soul King and existed in a powerless form without senses on a mountain until human townspeople found him and raised him. He would imbue others with health and strength but their fates were never to survive for long. That ability of his eventually opened his eyes and gave him senses. Eventually his power grew, and he formed his Empire of Light. Yhwach's personality is cold, but not excessively cruel. He rules his underlings with an iron fist and expects their loyalty and comradeship in return, going as far as to eliminate members who dare fight among each other. His nature as a self-proclaimed lover of peace extends to his hatred for torture and needless bloodshed, as well as deceitfulness. Yet, he is a ruthless fighter, leading the charge in every skirmish of his endless conquest.
