===Dweomer ===
Sorcerers are lone individuals. There are no wizardly Universities or covens. Wizards live alone, taking occasional apprentices, and are feared and revered by ordinary people. They are not common. The art of Dweomercraft is a long and demanding skill to learn, taking years to grasp the basics and decades to master even one Art. It is commonly believed that most Wizards know the secrets of extending their lives, and many are said to be hundreds of years old as this is the only way they can learn enough of the Art to be truly powerful. Some Wizards seek patronage with Lords or Kings, offering their services in return for sanctuary and funding to further their arcane studies. 

Dweomercraft is a dangerous art. Many say that it was the Magus, Lord of Lies who first taught man the Thirteen Sigils and the Ninety Nine Words of Lore, and it was one of his darkest tricks. It is said that every time a Wizard calls upon the Arcane lore to bend the world to his Will, he risks his immortal soul. 

Warhammer 2nd Ed has quite a good mechanic to make magic risky. 

===Alchemy and Thaumaturgy ===
While true Dweomercraft is a rare and dangerous art, Alchemy and Thaumaturgy are more commonly understood crafts. While a Wizard can call down Lightening form the sky, an Alchemist’s craft is more subtle. Most Alchemists or Thaumaturgists blend their arts with a more mundane craft, such as blacksmithing, leechcraft or calligraphy. A sword forged by a blacksmith skilled in the Alchemical arts may remain ever sharp, or may be unbreakable. A healing poultice brewed by a Surgeon skilled in Alchemy may cure all manner of infections or could heal a broken arm in mere days. A contract scribbled by a scribe skilled in the Thaumaturgic disciplines may wreak dire consequences on any who broke it. 

While more common than true Wizards, these rare folk are still scarce, and their skills are highly valued. Most find service with great Lords or travel the lands, selling their skills where they can. Many are still untrusted, for few understand their gifts. 

Black Sorcery and Necromancy and Witchcraft 
The Dark Path. The cults of the Dark Lord teach ungodly secrets to their initiates. Quick to learn, easy to gain power, yet impossible to master. The subtle weavings of Necromancy will always turn against their wielder in the end, for such is the way of the Father of Lies. Yet still, many believe they will be the one to harness the Black Art.
