Aether

Aether is an invisible, intangible substance which enables the casting of magic spells. It flows around the world in sympathy with the surrounding terra, flora, and fauna according to the principle of sympathetic attraction, or "like attracts like". In doing so, it forms streams of concentrated aether polarized toward one or more of the elements.

Aether streams are described interchangeably in terms of the color/element that dominates them:
