He did a bunch of stuff for Star Frontiers too, didn't he?
I think so, though it's not on the list at Tome of Treasures:http://tomeoftreasures.com/tot_adnd/roguesgallery/dykstra.htm
Huh, I don't think I've seen any of those before, and I'm not sure I've even heard the name before. Interesting.
Dysktra rocks - he *was* D&D for me back in 1991 with the Black Box set.
