A simple air mage showing his aura.

An aura is a mysterious phenomenal magical fixation. Those who are magic-users, have an aura and most can sense the auras of others. Usually the stronger the mage's magic is, the more powerful their aura's signal. Some mages can even cloak their aura, to avoid being detected by other magic-users. Sometimes casting magic or preparing to cast magic, a mage's aura becomes visible. This is most notable with Draven, when he is in combat he surrounds himself in an aura of fire.
