Sorcerers create magic the way a poet creates poems, with inborn talent honed by practice. They have no books, no mentors, no theories -- just raw power that they direct at will. Some sorcerers claim that that the blood of dragons course through their veins. It is common knowledge that certain powerful dragons can take humanoid form and even have humanoid lovers, and it's difficult to prove that a given sorcerer does not have a dragon ancestor. Sorcerers often have very good looks, usually with a touch of the exotic, that hints at unusual heritage.
A sorcerer usually keeps to the back of a party, damaging and neutralizing enemies with his wide selection of spells.
All simple weapons, and no armor or shields.
