This is a funny line from the beginning of The Tale of King Arthur:

And the thyrd syster, Morgan le Fey, was put to scole in a nonnery, and ther she lerned so moche that she was a grete clerke of nygromancye.  (p.5, lines 28-9.)

The Mythgard Academy class broke a number of staves of wit on the abbess of Morgan’s convent. (about 40:00)

It’s hard not to hear an echo of parents who send their children off to college, and then lament that they’ve come back with their heads full of funny ideas.  To a modern-day capitalist father, Marxism might be an exact parallel to black magic in medieval times.
