Runarch is the name given to one of the dragons whose decaying spirits feed the Otherworld. It was a specimen characterized by a peculiar chimerism, whereby the left side of its body is male and abino (white), and the right side is female and melanic (black).
Appearance
It is born as a baby dragon whose physical characteristics are perfectly sectored: the left side is albino, with a pink-red eye whose pupil is barely distinguishable from the iris, milky white scales, a very light-colored horn and spines, the right side is melanic, with an eye whose iris is bright green, black and opaque scales, and a caramel-colored horn and spines. The balance between the dimensions of the two parts of the body is increasingly lost as it grows: the male side develops more spines and horn, while the female side is less "decorated", but has more powerful muscles and a larger size.
Before reaching adulthood, the two parts of the body are completely disproportionate and seem to belong to two different dragons. The legs of the white part are more graceful, the body smaller and leaner, while the black part is noticeably more corpulent.
The difference in length of the limbs between the right and left sides initially makes its gait extremely awkward and later causes it to be impossible to move.
Runarch dies before reaching sexual maturity and his spirit begins to fuel the Otherworld, later bonding with two humans.
In spiritual form, Runarch has two different aspects: that of a fast, elegant albino dragon and that of a powerful, but stocky (and by many, terrifying) black dragon.
Personality
Runarch has not had the opportunity to develop his personality harmoniously, having lived a life of discrimination and physical vicissitudes. His greatest desire, to live a normal life and even surpass his brothers (and other dragons in general) in skill, is expressed in his obsession as a spirit, that of surviving and proving his strength.
Although Runarch did not have a healthy body, his mind is sharp and refined and his magical abilities are extremely extensive, split just like his body into two vast elemental domains.
Trivia
Despite not being an adult at the time of his death, Runarch was a dragon of considerable size. If he had grown to the maximum size allowed by his genetics, he would have been nearly seven meters tall.
Although he is called "Runarch" for convenience, this creature did not yet have a name before he died.
Having two different parts, not only in appearance but also in magical abilities and aura, Runarch had the potential to bond with two different dragoneers.
