The Witcher: Masquerade - One shot

Skilled mages can extract magical energy from the four elements, transport themselves long distances and heal, as well as kill, in the blink of an eye.

Their power and long lives grant them extensive scientific and political knowledge; in the latter respect, many mages are the equals of rulers.
