The above screenshot is from the Maiden of Vitality who is sparking green stuff out from here when Magni is helping you get the heart of azeroth.
I spoke to her and she says that, we know of Uldaman, Uldum, Ulduar and Uldir this xpac...
But Uldorus and Uldazi - As far as I know (and ive read all 3 chronicles and am a pretty big lore nerd) we have seen no other mention of these titan facilities.
It also has four other Uld...Uld...Uld...Uld... that they just doesn't seem to have names for.
I am assuming it is setting up for additional titan facilities in the future, any other thoughts/things I missed?
