Tasked with the researching of draconic lore, Lich Lord Venethrax is supremely well-suited to root out and destroy the Dragonfather’s dark progeny. Venethrax has dedicated his immortal existence to Toruk’s final war and is prepared to consume every blighted creature in charnel flames and blood. His mighty halberd, Wyrmbane, has dismembered countless draconic creations, and the lich lord’s very presence corrodes the world around him. That he now steps forth from Cryx is a dire portent, for it heralds the coming of war between the dragons.
