Mana

Mana is the primary, ubiquitous energy of the Manaverse. It is known as one of the fundamental driving forces of the Manaverse, existing as a harmonizing energy that facilitates terraforming in planets and the presence of life. Consequently, it is categorized as the Primordial Aether of the highest order.

It can be harnessed by beings and expended much like a "magical fuel" in order to cast Magic. Mana also acts as the primary energy source for souls, which require the aether for their continued existence.

The study of Mana is known as Mana Theory, or less commonly, Manalogy -- the focus of which pertains to the properties, phenomena, and behavior of Mana.
