Ideally, this will be the go to page for the campaign. Core and Tome material will be copied into the wiki, while other material will be referenced.
The front page of the wiki has a (currently growing) contents, and a link to character creation rules. The pages in red are, of course, not made yet. I’m working on that.
Regarding Tome. I will be using some classes, and a handful of other rules, such as Backgrounds, the proficiency rules, etc. These will be spelled out in a Houserules page of the wiki.
Once you’ve made an account, you can build characters on this site, so far as I know, though if the page is less than helpful, you can use Myth-weavers.com and link to the sheet.
