Even though Fantasy Flight Games have officially stopped developing Warhammer Fantasy Role Play 3rd edition, the players have continued to develop new resources. I recently found a new-to-me site, Daily Empire, a blog about all things Warhammer. The site has links to some fan-developed adventures, GM resources, tools, and more.
I found a new 120+ page adventure I might run my Warhammer group through: The Queen of Embers. It is geared towards players who are in the middle of their second careers, which is exactly where my players are.
Daily Empire also had a link to an expanded character module from the Winds of Chaos site. While this is really geared towards second edition WFRP, some of the rules and traits can easily be adapted to 3e to make character creation a little more detailed.
Stun to Strike is a fan forum for all things Warhammer. It seems to be a much livelier place than the Fantasy Flight WFRP forums.
Gitzman’s Gallery is a great place to find character sheets, link to Reckless Dice podcast, and the super huge detailed map of the Warhammer world.
