Leaders: Bazzalan and Jergosh the Invoker

The Searing Blade Clan is unique in that it formed after the founding of Durotar. The Searing Blade is merely another branch of the Shadow Council attempting to usurp Thrall's new Horde. They are led by the satyr Bazzalan and the warlock Jergosh. The Burning Blade and Argus Wake are the Searing Blade's sister groups. The Searing Blade has taken up residence in Ragefire Chasm, a network of caverns beneath Orgrimmar secretly attempting to subvert innocent members of the Horde.
