Just received a 1966 fanzine, FANTASY ILLUSTRATED #6. Contributing writer Steve Perrin [RuneQuest, Superworld] of 150 Rose, SF, CA 94132 has "The Origin of The Black Phantom," a character who apparently shows up in Perrin's later
RPG material.
However the references I can find are spotty: a blog with someone converting TBP's Superworld stats to Champions [I think], & a little bit on the author's own site, perrinworlds.com.
Anybody out there who's familiar with superhero
RPGs who can tell me more about this character, or about Perrin's early career?
