McAbre
A Mr McAbre is a senior bledlow, perhaps the most senior, at Unseen University. He has been responsible for the Ceremony of the Keys, held extremely loudly underneath the Bursar's bedroom window at two in the morning. Every morning. An account of a typical handing-over of the keys appears in The Last Continent.
He is not to be confused with the premium whisky manufactured by Bearhuggers.
