The sorcerer is in many ways the natural successor to the Mage - the amount of anguish these elite few can cause is simply staggering. While Mages spit out fireballs, I have seen Sorcerers summon raging infernos, and when a Mage casts chains of ice, a Sorcerer can reply with freezing blizzards and blinding snowstorms. Their talents have single-handedly turned the tide battle before; such is the power they possess.
A Sorcerer is not resilient however, and is one of the most defenceless classes in Atreia. In order to ensure they are kept alive it is often necessary to assign others to protect them, a cost that most are able to accept, given their extreme power.
