Okay! Greyhawk, Flanaess it is! Bandit Kingdoms to start out, but I think we may move on to another locale after a bit. Now, I'm not really wanting to start at 1st level, because I don't want our magic-user(s) to be horribly crippled for awhile. How about 3rd or 4th level to start? [Characters to be created using DMG Appendix 'whatever-it-is' ("I" maybe?) that details those rules.] Actually, just now studying the Grayhawk map to get a feel for the area of the Bandit Kingdoms, I've been struck by some fresh ideas that I like very much, even though they may not mesh well with conventional Greyhawk wisdom. Let's have all PCs come from lands surrounding Nyr Dyv -- Shield Lands, Furyondy, Duchy of Urnst, and County of Urnst, or even the Duchy of Tenh. Two or even several can be from the same region, no problem, just wharever strikes each player's fancy. We'll say that the PCs have just finished a mapping assignment for a Lord in the Bandit Kingdoms who wanted a reliable chart made of his domain -- for reasons that didn't concern you, he said.
