Warbringers



Ingame

N'Zoth in warbringers has circular, glowing pupil. That was unique and mysterious.

But N'Zoth's eyes in Crucible was just vertical slit pupil like ordinary monster. It's just boring eyes.

I mean who do you think made her warchief to begin with, its so painfully obvious
The old gods fear the alliance and the horde and the only way they can win is if they destroy each other. Even mentioned in the chronicles

Is the crucible entity confirmed to be N'Zoth? I don't know anything about that raid.

[Varjo410]

Maybe he just put in his fancy contacts for crucible.

[Rozz]

It's likely that his eyes can go between slits and circles like a cat.

Plus I think the round pupils were mostly for the "yolk/egg" analogy for Azshara since he reformed/rebirthed her in his image.
