Gary was a part of my learnings of the English Language. I learned words like "jeopardy", "goblet", "morningstar" (and "holy water sprinkler", for that matter), "stool", "mantlepiece" and more from him through the 1e AD&D books. He was my Doctor Seuss, you might say.
I hope Gary is somewhere comfortable, kicking off his "boots, low, soft" in front of a warn hearth and enjoying immortality. He has surely earned it!
