Ethernano

Ethernano is the term coined to name particles of Magic. Ethernano dwells inside all living organisms and throughout the atmosphere in both the Fairy Tail and Warcraft verses. Nobody knows when Magic began, or how Ethernano originated. To utilize Magic, a Mage must use their (as the case may be) power. Ethernano is the source of Magic Power for all Mages. Every Mage has a "container" inside their body that determines the limits of their Magic Power. If the case becomes empty, Ethernano will come from the atmosphere and enters the Mage's body and after a while, their Magic Power is restored. However, recent studies have identified another part of the Mages' Magic "container" that isn't normally used, and contains their dormant power called the Second Origin. If the power within this second container is released, then the Mage will receive an enormous boost in Magic Power, able to cast more powerful spells, as well as gaining increased magical stamina.

Living organisms cannot live in areas of extremely concentrated Ethernano, as it apparently has detrimental effects upon the structure of the body.

If a Dragon Slayer's element mixes with highly-concentrated Ethernano, the Dragon Slayer can eat it to achieve their Dragon Force.
