Onmyoji

Onmyoji were practitioners of onmyōdō, "a mixture of natural science and occultism," according to Wikipedia.  They were also known as Ying Yang masters and studied the five elements.  Some of the more powerful ones were supposedly capable of tying shikigami, a kind of spirit, to paper dolls and having them doing jobs around the house. 

More of my illustration to send to World of Darkness, for Mage, or such card games as Legend of the Five Rings.
