This diagram illustrates the conceptual framework of the Elthos World ... it includes the relative positions of both groups of Deities - the Cosmic Celestials and the Archetypes.
The Cosmic Celestials are represented by Zodiac and Planetary signs, while the Archetypes are represented by the Major Arcane cards of the Tarot Deck. Each Archetype has a corresponding Celestial. So if you were to imagine the two groups of Ekron overlapped they would form two disks divided into twelve pie slices, and both disks forming two concentric circles, as can be seen below.
The Cosmic Celestials are pictographically represented here on the back face of the Elthos Tarot Deck.
The Archetypes are represented in the Major Arcana of the Deck, and here's an example.
How this all plays out in terms of Elthos, the world, is that the Elkron are Cosmological Forces of the upper and lower realms of the Mind, and personifications of the Alignments to which they are associated. They war and ally with one another in accordance with their natures and the movement of the Planets and Archetypes as they perform the Dance of the Spheres. This all happens at the Cosmological level of the Campaign wherein the purposes and circumstances of the Elkron are charted.
That said, it has been very rare for Player Characters to advance high enough or deep enough to experience or comprehend the true nature of the Dance of the Elkron, or even more than a passing glimpse of it. However, it is there nevertheless, ever in motion, ever synchronizing elements of the back story with elements of the plot line. It's quite an exquisite system in many ways. Some day I do hope to rationalize it well enough to put into a book and explain to other GMs how it works, and what one might do with it. Until then, however, its to be taken as a kind of philosophic art that enhances the Elthos world in some mysterious way, as yet quite unfathomable to the Player Characters (or other GMs). Perhaps some day a particularly stellar mage will arise in the Campaign who will begin to make sense of it all.
