Circle of Decay
This cult was created by P.B. Wallace, noted author on the occult. His followers were urged to "relinquish your inconsequential individuality, bask in the truth of decay, and the world will be yours. Salvation in a world as debased as ours is only possible if you tap into the prevailing forces of corruption."
Quite simply, this is a cult of decadence dedicated to the spread of chaos. It turned out that Tiboro, ruler of the 6th Dimension, was behind the movement, since he will once again rule all with the coming of a new age of decay.
While this particular cult was broken up, the Circle of Decay will arise again and has been with mankind as long as he has been civilized (and as long as Tiboro wishes to rule the Earth dimension).
