The following is an excerpt from Primordials, Their Cults, and Histories: A Primer for Advanced Study from The Worlds Consortium University.
Before considering any serious study of this subject, it is imperative that certain facts are made evident.
Until recently a majority of scholars at WCU subscribed to the prevailing opinions of the Inter-world Society of Cosmoanthropology regarding the prevalence of cultures that actively engage in the practice of primordial worship. In short, the IWSC asserted that the rise of cults, religions, and other organized bodies portraying the primordials as living beings and/or deities was a rare occurrence across the multiverse. New research has shown this theory to be absolutely false, and provided some of the data needed to begin a more measured approach to the topic.
There are approximately twenty million worlds, an estimated 20-30% of all known universes as of the time this resource is published, in which the belief in primordials extends beyond the boundaries of mythology and into the lives of the intelligent species inhabiting those realms. The peoples of these worlds do not separate myth from history—chaos and order begin with capital letters, they are said to walk amongst them in the skins of lesser creatures, and the oldest stories these societies pass on tell of a war between the two. Often the totality of these beliefs fuels the development of entire cultures, shaping their worlds in diverse and unpredictable ways.
To study the role of primordials, their cults, and their vast histories, an awareness of these facts is required, in order to both contextualize the information as it relates to its origins and also avoid the natural tendency to minimize the importance of practices which we do not inherently understand. WCU recommends a complete reading and review of the supplemental documents at the end of this chapter, which include a series of myth-cycles from various worlds, a collection of images from the WCU archives and highlights from a number of histories.
