Ultraxion

More an abomination of dark energy than a dragon, Ultraxion has spent his short life absorbing the essence of captured nether dragons. Ultraxion is the only twilight dragon Deathwing has praised, and his arrogance is overshadowed only by the crackling energies surging through his twisted form. Loyal to his master, Ultraxion swears to bring about the fall of Wyrmrest Temple.
