Tome of Blighted Implements
The Scepter of Sargeras is known for the gleaming jewel that adorns its apex. Many theorize that it represents Sargeras's baleful eye, which caught only a glimpse of Azeroth before the fallen titan was ripped back to the Twisting Nether. But the truth is far different.
Soon after the War of the Ancients, Sargeras had a vision: the Well of Eternity imploded once again, but this time, it dragged him down to the very core of Azeroth. He was there for only an instant,
but in that moment, he saw Azeroth's slumbering world-soul--and in that moment, the world-soul opened one eye and gazed at the Dark Titan. He was enraptured.
Since then, the eye of Azeroth's world-soul has not been far from his thoughts. He commanded the eredar who forged the scepter to crown it with that lone, wondrous orb. Next to it, the eredar placed two nathrezim wings, a testament to Sargeras's conception of the world-soul: corrupted, demonic, and most importantly, his.
