Damon was an excellent student and did well. He never seemed to be sick and was successful enough to garner a scholarship. He befriended a Professor of History and decided to major in history and become a school teacher. Dr. Personaire helped him finish his studies and graduate with honors. The two remained friends when Flagg became a student teacher and later a High School teacher near the College. Unbeknownst to Damon, Personaire was also one of his 'Fathers'.

Young Flagg knew of his mother's 'Club'. He never knew the deviltry it consisted of. Finally, on his 30th birthday, he was to learn what it was. What he was. He took his fiancé at James request. She should know what the 'Club' was and become a member too, he was told. In reality, she was the Final Sacrifice that would bring Damon his full powers!

As soon as he learned what was happening, during the initial ritual, he fought back. Susan was still killed and Damon gained SOME of the power that was destined to be his. Since Personaire actually did the killing, he didn't get ALL of the power. His love murdered, Damon decided to give the Coven exactly what they wanted, a Prophet.

Personaire was the first Follower he killed. A fraternity in California was his next stop. During that raid he found some important FoG manuscripts and learned a great deal about how the 'Brotherhood' functioned. Armed with this knowledge and his Demonic heritage, the war against the FoG had begun.

His first mission pitted Damon against the Thunder Twins. The Prophet was vastly outmatched and he barely escaped with his life. While licking his wounds, Damon was found by the wizard Ravenclaw and recruited into Avatar's plans. That having fallen through, Damon finds himself in Germany, headed towards Berlin and his next stop against his life-long enemy, The Followers of Germanicus.

After months of hunting Followers and working with Balatar and the others, Damon learned that he was the most recent conduit between Der Nacht and Earth. As such, he had Balatar perform the severing spell on him, cutting off the source of the Followers powers and performing the ultimate act of vengeance. He briefly went to study magic under the tutilage of Balatar and Professor Möbius, but quickly learned that the magic he learned was only accessable to him when he was angry, which was counter to the teachings of control they were trying to give him. Eventually, he left to search for a new place in the world.
