Well World
Interesting premise. How are you doing it? Are you planning on mixing technology levels as they do on the Well World?
What about storyline? Is it the Well World? Or something similar? Do PCs assume some new form? What about all the psychological stuff that usually takes place in the novels? That would be rather hard to roleplay. What is the purpose of this world? Is it the root world from which all fantasy worlds derive their races, etc.? Or something else?
For creating new races, the heroes, monsters, and villains of Theah book has a good random monster generator as well.
Always liked those novels...
I think the two people are missing are the pair that take place AFTER Nathan and Mavra deal with the Krang in Gods of the Well of Souls....
I think one of the books was called "The Sea is Full of Stars".
