Sounds like a good idea, Mystic! Go ahead and add it.
Generally speaking, wikis encourage a "do first, then discuss" sort of process, especially when it comes to adding new content. If an article hasn't been created yet and you have the know-how to do so, go ahead and do it. If you see a typo, go ahead and fix it. Don't dramatically change someone else's text without talking about it first, but if you want to add new sections to a page or add hyperlinks to other articles (both of which I did on Ryx's bios for Murikeer and Malger) then go ahead and do so. If you think that something posted in the wiki is incorrect, post a message about it here in the forum and we'll talk about it.
One thing to keep in mind when creating new articles is the naming regimen. Articles in the Writer's Bible fit into five categories, each of which has a specific prefix associated with it that should be used when creating an article in that category:
Characters: Name files as "characters:name".
Events: Name files as "events:name".
Groups, Organizations and Races: Name files as "org:name".
Places: Name files as "places:name".
Technical info, which is basically anything that doesn't belong in the other categories: Name files as "tech:name".
Be sure to create links on the main Writer's Bible page to any new pages you create.
That's about it for now. Let me know if you have any other questions!
