Jeweled Scepter of Sargeras

The Jeweled Scepter of Sargeras is a powerful artifact that used to belong to the Dark Titan Sargeras. A demon in the Tomb of Sargeras located on the Broken Isles held the Scepter until it was killed by Ner'zhul's henchmen. Ner'zhul used it along with the Book of Medivh and the Eye of Dalaran to create the portals which tore Draenor apart. The scepter was in Ner'zhul's possession when he entered the rift, and while its current whereabouts are unknown it is likely to be held by Kil'jaeden, since Ner'zhul was almost immediately waylaid by Kil'jaeden and his minions after entering the rift, and the Scepter was not found anywhere near the Frozen Throne.
