- "It is true, of course, that genuine witches and wizards were reasonably adept at escaping the stake, block and noose [...]. However, a number of deaths did occur: Sir Nicholas de Mimsy-Porpington (a wizard at the royal court in his lifetime, and in his death-time, ghost of Gryffindor Tower) was stripped of his wand before being locked in a dungeon, and was unable to magic himself out of his execution [...]'"

Sir Nicholas met Lady Grieve while strolling in the park on the evening of 30 October, 1492. She was certain he could straighten her crooked teeth using his wand, but his attempt to do so backfired, causing her to grow a tusk. Sir Nicholas was immediately taken into custody and sentenced to death as a result of this mistake. Before being locked in a dungeon, his wand was taken from him, thus preventing him from using magic to escape.
