Asura

Shadeholders are dragon skins embodied by the Shade. When a dragon dies, the Shade can reincarnate it and use the body to its own benefit. They are essentially the Shade with the ability to walk, talk, and think. They have a hive mind ultimately controlled by the first Shadeholder to ever exist - a Skydancer named Naomi. They are more intelligent in groups, but they often prefer to work alone. A Shadeholder is able to cause conflict in clans by shadetouching a dragon. If a Shadeholder causes a war to break out between clans, any dragons who are killed in the battle surrender the years of life they would have had remaining had they not died in battle to the Shadeholder who caused it. Causing conflict is how Shadeholders keep their dragon bodies youthful. Shadeholders are tricky and maniacal, and they believe that they are god-like. They refer to themselves as "Prophets of the Shade" or simply "The Prophets." It is common for Shadeholders to take after bits of their body's original owner's personality. Even with the pieces of individuality that they express, a drone Shadeholder is nothing without its hive queen.

The firstborn in Naomi's first clutch, Asura is the Hive Queen's pride and joy. He was born to Arden and Naomi along with twin brothers for the sole purpose of spreading the Shade. Having never lived as a dragon prior to being possessed by the Shade, Asura has very little of a personality. Rather than being embodied by the Shade, the Shade was born into him. Naomi's very essence penetrated his body, spreading the evil deep within. He is prideful and fearless. He thrives in the shadows and he lies in wait for the perfect moment to interfere in a poor, unsuspecting dragon's life. Addicted to the feeling of power and control, Asura will stop at nothing to get his way. He is manipulative and mysterious - everything that a Shadeholder should be.
