Ethrealis

The Ethrealis is a lesser Being. It is a parasite infesting a Being through direct blood transmission or injection of pure Ethrealis. Since blood transmissions between Beings can turn lethal, especially between Beings of different species, it is highly recommended to extract Ethrealis. This lesser being is capable of shifting between the planes, being partially in the Earthen and Ethereal at all times. This allows a trained being to remove parts of their own Soul to create a Soulweapon.
