4th Edition D&D Core Rulebook
With the release of the 4th Edition of the Player's Handbook, Dungeon Master's Guide, and Monster Manual, you also get glorious new art. We've chosen a few pieces to showcase here for you, and they've been formatted into handy-dandy desktop wallpaper sizes so that your computer doesn't feel left out of the 4th Edition fun. (Maybe you should send a link to the one depicting a noncombat encounter to remind your least cautious party member that blithely strolling through even an "empty" dungeon isn't always a Good Idea.)
