An ancient emian viewed as a deity by the humans. Its not a god though, simply a powerful uniquely occurring Emian (elemental monster). 

In the distant past it worked together with a fire dragon, the Emian that came to be called Solanian to seal away the raging guardian of the world, Eclipstian, preventing the destruction of all life. It now resides at its half of the eclipse seal found on the eastern side of the continent.

Is known to have formed companionships (soul linking contract) with humans (it only forms one with one human at a time and won't form another unless their current companion passes away (unless its an emergency and two companions are needed)), using them as its hands and feet to prevent disorder in nature that could weaken the seal.

Its current companion is a young man who is known by the alias of "Moon".
