From the introduction: Dungeon Crawl: Risus uses the simple, easy-for-everyone Risus: The Anything RPG rules and folds in the expected elements of the classic fantasy setting. It's not the first take on fantasy in Risus, but it is the most complete. It eliminates the vague parts of Risus and the superfluous details of most fantasy RPGs and makes a smooth, easy to run game. These rules assume you know how tabletop role playing games work, and are at least familiar with the basic fantasy clichés.
