Legend of the Five Rings (often abbreviated L5R) is a fictional setting created by John Zinser, Dave Seay, Dave Williams, and John Wick and published by Alderac Entertainment Group in 1995. The setting primarily involves the fictional empire of Rokugan, though some additional areas and cultures have been discussed. Rokugan is based roughly on feudal Japan with influences from other East Asian cultures such as China, Mongolia and Korea. This setting is the basis for the Legend of the Five Rings Collectible Card Game as well as the Legend of the Five Rings Role-Playing Game. Legend of the Five Rings was also the "featured campaign setting" of the "Oriental Adventures" expansion to the third edition of "Dungeons & Dragons", though this book is now out of print.
