This is a biggie. An entire sourcebook for AD&D based on the hugely successful "Belgariad" (and to a lesser extent the "Mallorean") by David Eddings. This book features everything you'd expect from a sourcebook - character classes, specialities, a Belgariad timeline and a description of the known lands. This really is a fairly mammoth undertaking.
