Greetings,
I have been out of the gaming thing for quite a while, but my favorite world is Greyhawk.
I was unaware of the Paladins of Greyhawk, so thanks for tipping me off to that.
Something else that you may want to research, to add some different flavor to your Paladins; Paramanders, and Paramandyrs.
...ders, is a LN type, and ...dyr is a Psycho. Really neat stats and feats. Way off the beaten path for Paladins and if played properly, a nice / nasty surprise for the PC's.
I will dig into my collection of mags and see what I can find as far as the issue numbers.
Good luck and happy hunting.
