Since races have pages and soon places of the Witch World will be getting entries, I thought of a few other possible pages:
People of the Witch World. The Warding of the Witch World has a family tree. Is there a way to re-create it on here? How about entries for main and re-occuring characters? Their profiles could have brief descriptions and chronological appearances? These could also link to the Race pages as examples of each race/if the character is inter-racial, and the "places" pages as to where they're from and traveled to.
I also thought of a "suggested chronological reading order" page as a neat reference for someone first taking the plunge into the Witch World.
Another way of cross-referencing could be to list the authors with links to their stories to see who was responsible for what.
Make sense? A lot of work but hey, it's a wiki. lol!
