Cosmology!
Included are three diagrams.
The first is that of the Eldamon Elements. It is included as a guide for the Eldamon Elemental Symbols as they are used in the other two diagrams.
The second is a conceptual map of the cosmos.
The third shows how the four basic elements formed most of the other elements.
Eldamon
As the cosmology map relies on the Eldamon elements I think an explanation of these creatures is warranted. Eldamon are creatures made of elemental fragments.
Cosmology Origin Story:
At the beginning there were four spheres, each made of a single distinct element. These four primordial elements were Fire, Earth, Water and Air.
The four spheres all collided creating an explosion.
The remains of each of the four base spheres were flung outwards, along with the newly created composite spheres - Metal (Fire + Earth), Wood (Earth + Water), Ice (Water + Air), and Lightning (Air + Fire). These eight spheres form the elemental ring.
Where the collusion occurred the greatest mix of the four base elements formed briefly into that of Life and Death before combining into a single sphere - the Prime sphere. As life sprung into existence the three other essence spheres formed; Body, Mind and Spirit.
Two other spheres formed from the fragments, that of the Darkness and the Light spheres, reflections of the Prime Sphere.
This is a condensed summary; see Cosmology Full for the full write-up of each sphere, the dimensions, cosmic forces, and altered spells/rituals.
