The Elenium and Tamuli series of novels provide a good background for role playing for the intrepid adventurer. Here are some guidelines that I provide for my gaming group for playing in this world of David Eddings using the GURPS gaming system.
GURPS Basic, GURPS Compendium I, GURPS Magic and GURPS Grimoire were used to construct these guidelines. If you don't have GURPS yet, please pick up the GURPS Lite rules for a quick start.
