Note: I am slowly converting Nephilim, an old Chaosium game, over to Dresden Files FATE. I am just flopping all the posts on my blog because I can tag and collect them all later. This stuff is in no particular order. You can buy Nephilim in PDF from DriveThruRPG for ~$17. You should also buy Dresden Files RPG.
