I'm far more interested to know about the chairman who appointed Dire Crowley as headmage than I am in the length of Crowley's tenure.
Crowley's been doing this for a long time, but not as long as Skully was a student, as he says, which could have been ~530 years ago.
So Crowley could have been the headmage for only a century or two. Even still, who's the chairman, and why Crowley?
