Elemental Energy is the resulting composite of Root Energies and or other Elemental Energies.

In most situations Root Energy is too fundamental to sustain itself alone: Sol and Nyx cannot exist without their polar opposites. Vir as motion and heat will dissipate without a conductor. Osa gives form, but only if there is something else to be formed. And Tek cannot apply its order if there is nothing to receive it.

This all means that the Root Energies are drawn to each other and together they form a whole, an Element. This whole could be many things, it could be a gust of wind, or a stone in the sand, or a bubble in a pond.
They will then come together with other Elements to form ever more complex Elements in an endless dance of creation.

But as these Elemental Energies form deeper combinations they bring the risk of collapsing over completely. If the right Elements find themselves together in the right ways one may tear the other apart, or they might both annihilate each other. The Energies composing the destroyed Elements are then released, free to recombine in the future.
