Elements are officially named now. If I missed any, we'll change them, too:

Light - Luma
Sound - Sona
Psychic/Engery - Aura
Air - Aera
Water - Larga
Shadow - Umbra
Earth - Gaiia
Time - Chrona
Fire - Fyra

Each element has several kinkds of spheres but they don't need to be officially listed. For example a Love Sphere would be Aura element, Rock Sphere Gaiia element... etc etc.
