 By 1974, the group of "D&D" players sometimes included over 20 people, so Kuntz became the co-dungeon-master, allowing each dungeon master to referee groups of only a dozen players.Kuntz brought in some elements of his campaign into Greyhawk, and some levels of El Raja Key were incorporated directly into Castle Greyhawk.After Gygax formed TSR in 1973 and was hired as the company's first full-time employee in mid-1975, he was soon followed by Rob Kuntz, Terry Kuntz, Tim Kask, and Dave Megarry.
