This is the seven elemental/chakra system I've developed for my developing story :P, I could give this long winded explanation but I'll spare you, just look at the pretty pictures :P

Okay okay, here it goes.

Light = Power over energy, essence of the star. This is the power to control the enegy of motion and lightening

Heaven = Power over wind and sound.

Sol = Power to manipulate heat and fire.

Zen = Power over existance, forbidden and conciderd too strong for any person to ever controll. Any attempt at making a sigil to controll this is an offence sutable for death (in the story) and many have actualy died in the attempt to controll it. For a person, this chakra is replaced by "Yin" or "Yang" essence of being either woman or man.

Lun = power to manipulate cold and water

Earth = Power of maipulating matter, more to the point the production of an inky black shapeless material.

Stone = Power of Gravity, able to change the direction of Gravitational pull.
