Hieronymus Sum

Professor Hieronymus Sum is the professor in charge of the Active Combat Engagement program, and the man to whom the PCs will be reporting.
Professor Sum is an extremely busy man who only makes time for his ACEs, who he treats firmly but kindly. He has become a father figure to many former members of the program and follows their exploits with interest. He can point PCs to where they need to go to research their upcoming missions and give hints as to what they might need to pack.
Professor Sum’s personal life is largely unknown to students.
He has absolutely broken Barry's fingers within hearing distance of the gang.
