Lords of Creation: Ancients of the Void
Wizardry is a form of Battle-Magic, invented by Mollana Heyes in Klein. Based upon the principles found in texts describing the Creation of the World, and the Forgotten Gods, Wizardry involves channelling vast amounts of elemental power; be it lightning, fire or some more esoteric element. There are some non-violent uses for this ability, a skilled Wizard could refine their control to raise a wall from the earth beneath them, or command the air to let them fly through the skies. But these are hard to master arts. Most uses of Wizardry are found in battle, throwing mighty fireballs or lightning bolts towards your enemies.
The other major point to note is that Wizardry takes vast amounts of inner self control. A maniacal, emotionally unstable wizard runs the risk of destabilizing their own spells, incinerating themselves and those around them rather than just the enemy. This results in only Wizards with few options (or immense personal cruelty) allowing passionate young heroes to study their magic. It very rarely, if ever, ends well.
Currently, there is only one Wizardess in existence: Mollana Heyes, of Klein. She is still perfecting her powers, and thus has not yet begun to teach what she has learned to others.
