Elemental Energies chart -- one of the many ways that the fundamental structure of life and magic is viewed throughout Tamal.
This chart was developed from a Nybilic notion of how the elements of the world interacted. It is also called the Gemstone Chart, as each major universal element is assigned a mystical sign and a gemstone. It is often used by alchemists, though it remains something of a scholarly conceit. There are, of course, other competing theories as to how the world works. The most popular is actually the Aegirean "Tree of Life", but I have yet to catalog that into my notes.
