So I've avoided spoilers of 8.3..thus far, so if this had be alluded to already, apologies
But I just noticed a small thing, and it got me thinking. Helya's necklace or neckpiece has what appears to be..a eye of N'zoth on/in it? We know Helya isn't out of play, she's out their getting stronger, She is a death Entity and she has the power to bring back the dead rather quickly as the Kvaldir let us know
SOOOOO could it be possible N'zoth, Helya and Sylvanas are working towards similar goals, together? or against each other for the same thing? Or against a larger unknown force? Or is it just a simple design?
