Stephen studied anthropology at Harvard and taught at Wellesley. He was a powerful wizard from a distinguished magical lineage, but he didn't flaunt his power. Stephen usually was easygoing, stubborn, and other witches thought he kept secrets. He died on a trip to Nigeria with his wife, Rebecca Bishop.
