Aidonescus

Aidoneskus walked slowly, his heavy footsteps audible from a distance. He was now wearing no knightly armor, only a long black-and-silver hanfu. His steps were slow, and his gaze was heavier than steel... He was bored wandering alone, in the wilderness where he lived... He slapped his tail angrily against the ground, leaving deep furrows in it. Aidoneskus occasionally glanced around, listening to the sounds of nature, as if afraid someone would notice him.

Aidoneskus is rude, often rude and sarcastic, his main goal is to exterminate all the dragons of light, which he has been working towards for over a century (half-dragons are immortal unless killed by weapons or hunger.) and hones his skills in order to overthrow Peresvet from the throne of the half-dragons of light, and plunge their world into complete darkness.
