Mages, the most common of arcanists, are found all over Azeroth. They focus on magic that creates and that changes things, most often with the purpose of damaging their enemies and boosting the power of their allies. Such beings can obtain a familiar, which is a normal animal that gains new powers and becomes a magical beast when summoned to service by a mage, while others choose to become focused mages. Mages also understand the workings of arcane energy so well that they can counter most magic with great effectiveness. An adept mage who has dedication to and natural predilection for one of the schools of specialization becomes more entrenched. At this point the mage chooses either evocation or transmutation as a preferred school, and casts spells from his chosen school. The mages of the Kirin Tor first mastered the arts of casting spells using the elements of ice and fire. Mages are also known for being able to summon elementals, usually water elementals, but can also summon air, earth and fire elementals as well. The greatest mortal mage ever to live is the naga queen Azshara, who still lives. In fact, she may no longer be mortal.
The first known mages on Azeroth were elves, before the breaking of the Well of Eternity and the exile of the high elves, who lived on the shores of the Well of Eternity and wielded its powers.
