This is a reimagining of the Inner Planes. In it, there are 6 elements. Fire, Water, Earth, Air, Light, Darkness, Life, and Death. Death and Darkness are based on the Negative Energy Plane. Life and Light are based on the Positive Energy Plane.
Quasielements resulting from this:
Air+Light=Thunder
Air+Life=Breath
Air+Darkness=Fog
Air+Death=Disease
Earth+Light=Crystal
Earth+Life=Wood
Earth+Darkness=Dirt
Earth+Death=Barren
Fire+Light=Energy
Fire+Life=Soul
Fire+Darkness=Ash
Fire+Death=Ember
Water+Life=Blood
Water+Light=Freshwater
Water+Darkness=Oil
Water+Death=Saltwater
And where all opposite elements intersect, the Primordial Plane.
I will update this periodically.
That's eight.
