Murlynd sounds like a lot of fun and has some great history to him. If I ever get to play in Greyhawk, I want to make a paladin/artificer of Murlynd.Gygax explains in his interview with Lynch that Kaye was invested in D&D from the start:
...when I came up with fantasy medievals, Don knew I had something special going. In late November of 1972 I wrote the first draft of the D&D game, and Don was one of the small group of initial players: son Ernie, daughter Elsie, and two teenage boys, Rob and Terry Kuntz, forming that whole.
Kaye played in the second round of playtesting, creating the character Murlynd alongside Rob Kuntz's Robilar and Terry Kuntz's Terik. Gygax explained how character names tended to be variants of their own names, but Kaye took a different approach:
Don Kaye was a semi-exception with Murlynd. As I became a bit more engaged in the broader possibility spectrum of the game I did a more seriously considered PC, as already mentioned. That became common with most of the veterans in our group around that time.
Murlynd was not a simple character either. Kaye played a magic-user:
He was well known for using his boots of levitation to rise above an ongoing outdoors battle only to become a floating target (Gary and I used to say, "barrage balloon") for missile wielding monsters at ground level. He also wielded a staff of power and owned a small house in the City of Greyhawk.
Kaye's passion for Westerns spilled over into his gaming as well:
Don was a great fan of the Western and an avid supporter of the Boot Hill rules. He designed several scenarios for the LGTSA to play the rules in, including one which involved the 'Black Bart' gang. otherwise, this is another remembrance added to the super-characterization he became via EGG.
Murlynd visited a Wild West world and returned with a Stetson hat and six-shooters; the universe of Greyhawk specifically prohibited gunpowder from working, but Gygax made an exception for his friend by turning the six-shooters into magical weapons, as described by Gygax in "Greyhawk's World" in Dragon Magazine #71:
As noted, Murlynd is prone to carry technological weapons (variously called “45s”, “six shooters”, and “hog legs”) which he is able to employ in both his left and right hands. His special aura enables these devices to function even on Oerth, for instance.
Kaye's interest in Westerns went beyond Murlynd. His passion built the foundation for a Wild West role-playing game:
...Don began to look forward eagerly to doing a Wild West RPG. He planned to draft rules as soon as he could quit his job to work for TSR. We projected that would be possible in about a year or so. Don was very happy.
Gygax would publish the wild Boot Hill posthumously in honor of Kaye.
So, thoughts or experiences using Murlynd?
