Enlightenment is one of the many victory conditions in the card game available to a player, and occurs when a player gets all five elemental rings of Earth, Fire, Air, Water and Void into play. This is called an Enlightenment Victory.
Near the end of the Diamond Edition, players were given a choice between two paths for the release of the next base set: Lotus Edition, and Dark Lotus Edition. This choice was given to the winner of GenCon Indy 2005, Scott Rixson. Should the latter have taken place, the enlightenment victory condition would have been removed from the game completely. However, Rixson chose for Rokugan to retain enlightenment, and so it was thus saved.
