Among the powerful, reclusive mages of Halruua, each Elder receives a skyship and the secret of recharging it. (Jeff Butler cover for Forgotten Realms supplement FR16: The Shining South by Tom Prusa, TSR, 1993)
"Why is this Mutant Smiling? New body parts in Gamma World gaming" -- Jeff Butler art for John M Maxstadt's article in the Ares section of Dragon 96, April 1985. After TSR bought out SPI and its assets, including Ares magazine, Dragon included an Ares section with its own separate credits distinct from the main Dragon credits. Somehow Butler's name was missing from both in this issue.
