I've been wondering... you see, I'm well aware that "wand cleaning accidents" are often code for death-by-duel. Any idea what actually happened to Avery?

To say nothing of some of the other high-profile deaths of late. Glendower, Bode...

Is there anything I should know? Normally, I would ask my father, but things being what they are with his situation, that doesn't strike me as the best source to turn to.
