Administrative Sergeant Clay Buxton controlled all the online betting and illicit flow of information from Whateley Academy. He was a man that no one saw, but who controlled great power in his own right.
At 6' 1" and a slowly softening 210 lbs. he did not seem to be the man of influence that he actually was. Graying crewcut hair and a false friendly attitude tended to soften the steel hard determination to succeed at any cost attitude that was his.
Chief Franklin Delarose and Headmistress Carson are aware of this, but choose to mostly tolerate his behavior because information leaks are a necessary evil and Buxton at least has some respect for serious security issues. The man may be corrupt but he knows his business.
