Retromancer

A form of wizard or sorceress who uses direct influence magic, a form of magic that uses the imagination to produce a desired effect. The reason for the term retro is that the limits of your powers often coincide with past experiences and memories, which in turn, forms a clear picture of a desired effect into your mind, and then into reality. Therefore Retromancers grow stronger with age and wisdom rather than trained use of their abilities.

Turning water into wine.
Turning coal into diamonds or gold.
Turning one material into another material, or fabricating a material from thin air.
Retromancers are often confused with alchemists.
