- "I've heard that you are responsible for banishing Andariel back to the Burning Hells. I'm impressed, stranger. That couldn't have been easy. My name is Drognan, and I know what you're up against, my friend. You ought to look over my inventory of items for trade."
- It was speculated that Drognan is really Horazon, one of the most powerful mages in history, and the leader of the Armies of Light, opposite his brother, Bartuc the Bloody, in the mage wars, but this was disproved in the Diablo Novel: Legacy of Blood.
