Henrietta Drononanon

Henrietta Drononanon was the former History of Magic teacher at Solaris Academy of Witchcraft and Wizardry. She was the oldest teacher at SolAc until her death, which was sometime between Seasons 7 and 8, and really lived up to her last name: her voice was so overpoweringly boring, anyone who listened would fall asleep within ten minutes, five in warm weather.

Mrs. Drononanon is also noticeably one of the few staff members at Solaris Academy who is a Squib.
