Gregory is a man of Swedish decent, of medium build and height. He favours old fashioned clothes, and is often seen wearing either a tweed three-piece suit, or white surgical coats. He speaks with a mild Nordic accent.
A former physician in life, he has become obsessed with the Vampiric condition. He has gained quite the reputation thanks to his research.
He enjoys the protection of the Traditionalists, who see him as a valuable resource. Gregory in turn offers any who consult him the breadth of his knowledge in return for boons. He has even gained favour with the Prince thanks to his broad understanding and insight.
He has a sprawling mansion in the Hollywood hills where he reportedly maintains a state of the art medical facility.
