Velkyn

Velkyn is the Draconic Sovereign of Darkness. He watches over all humans who use Dark magic, and is the leader of the Dark Dragon Brood, and also the Undead Dragons.
For over a thousand years he was imprisoned in the Abyss by Zaikerik the Betrayer, until being freed by Mina Frost and taking on the guise of a cat named Fishbones in order to befriend the Saviours.
Though he aided the Saviours during the rise of Zaikerik, and befriended Ayla Vanderstone, the dragon still has questionable morals, and is not respected by many of the other Sovereigns due to his lazy and deceptive demeanor.
While trapped in the Abyss with Livia, they produced a child; Lunolyn.
