We've known for a while thanks to screenshots and data from
World of Raids that
M'uru was the
long-expected Dark Naaru boss of the Sunwell. As a lore fanatic and Blood Elf fan, I wondered how they'd explain his disappearance from Silvermoon and his reappearance at the Sunwell, so when tipster James let me know something was up in Silvermoon on the test server, I had to head out immediately and see for myself. He was right: M'uru is no longer in the not-so-secret chamber below the Paladin's guild headquarters in Farstrider Square in Silvermoon City, nor is
Lady Liadrin, the founder and matriarch of the order.
Instead, I found the Blood Elf Magisters who had formerly contained the Naaru kneeling or sitting on the floor, or standing in a woozy, stunned daze.
Magister Astalor Bloodsworn was the only one who talked, cursing
Kael'thas and his Felblood troops for stealing away M'uru, and saying that Lady Liadrin had gone to look for a new source of power for the order.
And yes, she does show up elsewhere to claim that new source.
