The Dark Convention is a group of wizards in North America who are, depending on one's source of information, an evil cabal of warlocks intent on destroying civilization, or a group of men who feel disenfranchised by not being in charge and want to take power away from the men who are in charge. The librarian of the Charmbridge Academy, Mrs. Minder, claims that the Convention are "a bunch of bitter old cranks boiling death-draughts in their cellars."
