Justin DuMorne

Justin DuMorne was a human wizard and former Warden of the White Council. He was mentor to the young wizards Harry Dresden and Elaine Mallory.

Early life
Justin DuMorne was once a Warden of the White Council. He had apprenticed under Simon Pietrovich.

As a former Warden, he participated in the chase after the necromancer Heinrich Kemmler. During or after this, he found and took the skull-bound air spirit owned by Kemmler at the time, but kept its discovery and retrieval a secret from the White Council, who thought it had been destroyed. Some time after this, DuMorne left the Wardens.

According to Ebenezar McCoy, DuMorne was a contact of Margaret LeFay.

Later life
DuMorne adopted and apprenticed ten-year-old orphaned wizards Harry Dresden and Elaine Mallory, shortly after they came into their powers. He began to teach them the basic principles of magic.

Justin was abusive, but though he seems to have adopted the teaching philosophy of "pain is an excellent motivator," he was more emotionally abusive and manipulative than physical. He encouraged a distance between them and other children, and was gradually training the two of them to be able to use magic in violence without realizing that it was wrong, so that they be his personal enforcers.

One day, Justin turned Elaine into a thrall. He attempted the same thing on Harry, but Harry escaped. Justin sent He Who Walks Behind after him. Harry came back to save Elaine. He preformed a fire spell, burning the house down, killing Justin.
