Witch

"Some gain power through study, some through devotion, others through blood, but the witch gains power from her communion with the unknown. Generally feared and misunderstood, the witch draws her magic from a pact made with an otherworldly power. Communing with that source, using her familiar as a conduit, the witch gains not only a host of spells, but a number of strange abilities known as hexes. As a witch grows in power, she might learn about the source of her magic, but some remain blissfully unaware. Some are even afraid of that source, fearful of what it might be or where its true purposes lie."
