Hi Colonel, it's been quite a while since I've posted to this forum and was just reading through what I had missed. You can tell from the quote, perhaps, that it's been some time since I visited this thread.
Anyway, I've seen you make comments like he above a few times before but I have a question as to how you envisioned this to work in your home campaign. Did you envision demi-humans, for example, being native to a parallel Prime Material Plane and immigrating to Oerth at some point? Was this immigration a one time occurance in the past or is it something that can still occur? Given the rather long life spans of some elves (e.g., Grey Elves) was it possible that some of these creatures who came to Oerth in the initial wave were still alive during the playing of your campaign? Lastly, did you have an idea about
when the demi-humans (and other creatures) entered Oerth? (In the Greyhawk guide it lists 5050 S.D. as the date when humanoid mercenaries were first employed. Certainly such creatures were already on Oerth for some period before this.)
Sorry for the lengthy questions
