I also decided sometime over the past week (don't remember when exactly) to set the game in Ethangea, specifically in good old Khaldun. I have a couple of adventure ideas already, so assuming the character group gels well, this could be a great campaign. I'm doing this for two reasons: first, because I think it's a good setting and lends itself to the kind of adventures I have in mind to run, and second, because it will hopefully give me a reason to flesh out and concretize (is that a word?) more details about the setting, for my post-SJ writing career.
(I have mentioned, I believe, that one of the things I want to do after the strip ends and before the comic book starts, is to write a few books. One is Brigid and Greg, one is Michael Macbeth, and I have three ideas vying for prominence in Ethangea.)
I haven't decided exactly if (or how) I'm going to deal with things like the old race or werefoxes in the S&S SAGA campaign; these are established parts of Ethangea in my mind, but are intended to be such rarities that I don't want to just toss them in casually. I may just leave them out to start with and fold them into the game gradually as the dictates of the campaign require.
PS -- Note to myself: "Black Flame" has too many specific real-world meanings. Change that. How about "Black Fire" instead?
