Biography
For a long time Wizro was merely a sentient malevolent ring, who would trick people into wearing him, and then draining their energy. Thanks to Shia's dark magic, Wizro was given a body like that of a dark sorcerer, and he pledged his allegiance to her, as she was now like a mother to him. He aided her and her other ally Valga in their war on Hyrule.
