From the introduction:
The SenZar Cosmos exists beyond what mortals call "The Dream Barrier," or the mystic veil which separates the magick-blind cosmos of Terra from the magick-rich cosmos of SenZar. So far as humanocentric perceptions are concerned, Terra acts as the center of its cosmos. This may or may not be true. However, SenZar is the center of its cosmos; it is the prime world from which all other prime or center worlds derive. SenZar, as the prime world, was the homeworld of the Sidhe, those magickal creatures born of The Dragon, or life force of all things. The Sidhe ruled the primeval world of SenZar for untold millennia in peace and harmony until the advent of Namo, whose pure Sidhe essence was corrupted by one fatal flaw: ego.
