Also known as
Ether (エーテル,
Ēteru?), it is one of the Five Great Elements. Ether is also called the
Fifth Imaginary Factor (第五架空要素,
Daigo Kakū Yōso?) according to the teachings of the Mage’s Association. It combines itself with any of the other four Elements in order to actualize the
Mysteries of
magecraft.
[32]Ether is the artificial
magical energy that forms the basis of modern magecraft, although it did not exist during the
Age of Gods.
[33] Although amorphous and incapable of materializing by its own power,
it is what allows Spirits to take a material form. Paracelsus assigned a black-purple color to it following Tattva.
[29] The Ether elemental affinity is exceedingly rare, and in the hands of a high-ranking magus can be used to interfere with the cornerstone of magecraft, the Fifth Imaginary Factor Ether itself, and dismantle the magecraft of another magus. When combined with Earth, the essence of gemstones, any other elements can be extracted from jewels.
