Just wanted to let everyone know about some additional resources that have come out since the initial Core books (and since we all built our characters).
One of the best sites we’ve found is The Ninth World. Here you will find a wealth of new (mostly player-created) materials. I’d definitely recommend exploring the site- it’s very interesting! Pages of particular interest may be the list of new descriptors and new foci. Of course, any of these you might be interested in using must be approved by your Almighty GM, but most of them look pretty reasonable to me (but what do I know, I’m just the GM’s assistant ;) )
