Found him in the pages of an old issue of White Dwarf I found in my stacks of old cool stuff.
Issue #26 to be exact, from...you guessed it..."back in '81" (Aug/Sep 1981), had a nice little writeup I could have used "back in..." Ok, I'll stop doing that (for now).
Here's a shot of the 1-pager "Lizardmen as Player Characters" by Roger E. Moore and Michael Brown, from that issue:
The article mentions two novels as inspiration for such a beast as a PC: "The Doomfarers of Coramonde" by Brian Daley and "Quag Keep" by Andre Norton. "Doomfarers" I have no recollection of, but "Quag Keep" is an old favorite of mine, and maybe I unknowingly used Gulth, the lizardman in that story, as inspiration for my guy...dunno.
I haven't read "Return to Quag Keep" yet, but I do linger on it, every once in a while, at good ol' Barnes&Noble.
