Ed Greenwood, Dave Gross, Erin Evans, Erik Scott de Bie, Ari Marmell, Gary Gygax.
Gygax in particular deserves a lot more respect as a fiction writer than he usually gets. His story sense sometimes wasn’t as sharp as the editor in me wishes it was, but his ability to capture setting and character with a rich, nuanced prose shows off the influences of the fantasy writers he loved, and gives some fresh context to the inspiration that many of those writers had on Dungeons & Dragons.
