Aron originated the Traveling Players of Gilean concept. As I recall, he met Margaret at a con and they talked a while, revealing that Aron was a Dragonlance fan. An anthology was mooted, and Wizards bought the concept.
I was asked to collaborate with Aron and turn one of his story ideas into a novella for the anthology. Though we talked on the phone many times, we couldn’t agree on a plot. Our differences weren’t acrimonious; he just never could settle on an idea. Every phone produced a fountain of ideas, plots, subplots, and characters. Every time I worked Aron’s concepts into a workable outline, he wanted to add more, change things, etc. Eventually I gave up. I believe he did end up collaborating with Jean Rabe.
He was a nice fellow, effervescent, bursting with humor and ideas. I just couldn’t pin him down to the mundane task of agreeing to a workable plot. I regret his passing; I never heard from him after The Players of Gilean was published.
