Thanks to the magic of the Internet (and a little tool called Google Alerts), I have discovered a brand new fantasy setting for Risus called Hawkmoor. There have been many fantasy settings developed by the members of the Risus community over the years (a fair number can be found at the Risusiverse), but Hawkmoor is one of the finest that I've seen. The website is handsome and functional and the description of the Risus implementation is succinct and elegant. The setting's author, James D. Hargrove, deviates only slightly from the standard rules and I especially like his approach to wizards and priests. If you want to play Risus with a distinctly old school D&D feel, I highly recommend checking out Hawkmoor.
