Generally, in fantasy, Wizards get their power from studying arcane magics and drawing their power from mana/spell slots/glyphs/whatever. Witches get their power from the land they claim as part of their coven and the occult rituals they perform.

Wizards abandoned their school. Witches used to be women using sorcery, who were forbidden from the schools. They were both damned. Now though, thanks to our holy aspect emperor witches have been adopted with the other schools and are no longer damned. Truth Shines!
