Phil Flagagan is the principal of Marnie's school. He is a descendant of an army known as the Knights of the Iron Dragger. He originally helped Edgar Dalloway get the Cromwell's magic, but abandoned that job after he fell for Aggie Cromwell. Phil also admitted that he couldn't fit his finger into the ring that was associated with the Knights of the Iron Dagger.
Edgar Dalloway found him and revealed the past of his family, gaining Phil's help in trying to permanently seal the portal to Halloweentown.
Halloweentown High (2004)
- "For centuries, my family has been keeping a vigil, a vigil to ensure that our world remains pure of the magical. I'm the last remaining descendant of a noble order."
