Weapon: Ulthalesh, The Deadwind Harvester
The first necrolyte to walk the world of Azeroth, Satiel, was given this scythe by the titan Sargeras himself. It grows in power as it draws souls from its victims. The Harvester earned its name as Satiel methodically drained all life from the hapless inhabitants of Deadwind Pass, creating a potent magical nexus there in the process. Hunting down Satiel, the Guardian of Tirisfal turned the scythe on her, sending her soul to join those of her victims. Eventually the Dark Riders recovered the weapon and secreted it beneath the tower of Karazhan.
Weapon: Skull of the Man’ari
Before the eredar served the titan Sargeras, one of their greatest leaders, Thal'kiel, had unprecedented skill with summoning and binding magics. Driven by ambition, he reached into the Void and was answered with knowledge of dark creatures unlike any the eredar had seen before. His audacious power grab infuriated the demon lord Archimonde, who struck him down, then had his skull gilded and placed on display as a warning. Today the dreadlord Mephistroth uses it to enhance his ability to summon and command demon armies for the Legion.
Weapon: Scepter of Sargeras
Created through incredible effort by hundreds of Sargeras' servants, this scepter can rip open dimensional gateways between worlds. It was entombed beneath the sea for centuries, then used by the orc shaman Ner'zhul to open the portals that tore the world of Draenor apart, leaving behind the shattered realm of Outland. The scepter was finally secured by the elite magi of the Kirin Tor. Unable to destroy it, they hid it away in a magically protected chamber and put it under eternal watch to prevent it from ever being used again.
