Today’s topic: The Kabbalistic Tree of Life as a decorative element in Roleplaying Games. The association is suggested both by Kenneth Hite’s many references to it in his conspiracy column in Steve Jackson Games’ Pyramid online magazine, and by the nine spheres that figure in the game “Mage: The Ascension”.
Specific links are a page about the ten sephiroth and a detailed article about The Order of Hermes in Mage, which matches the spheres to the sephiroth.
Personally, I think that “Netzach” (“Eternity”) should belong with “Time”, not “Life”, both because of its name and also because its other associations fit The Cult of Ecstasy, the Mage tradition most associated with that Sphere. But since the article only deals with the Hermetic mages, he misses that.
