What do you think the current status of the Pillars of Creation are? We know the Tidestone was stolen by the Naga, but the other ones are not mentioned at all. Do you think they were reclaimed after the events of the Legion War by their respective peoples?
I could very easily imagine the Highmountain Tauren asking for the Hammer of Khaz’goroth back, as they have been responsible for keeping it safe (and using it when needed) for the past ~10,000 years, and while they were more than willing to hand it over to protect Azeroth, I don’t think they would have considered that a permanent affair and likely would have requested it back when it was available.
Much the same for the Discs and the Nightborne, who would very much like the return of a powerful magical artifact for their own people. Seems the kind of thing that Occuleth would love to be able to study in extensive detail.
Odin wanting back the Shield seems rather obvious, and based on his wonderful characterization, I’d be surprised if he didn’t more or less just demand it back.
The Tear of Elune if anything is the trickiest, because I could see both the Night Elves and Green Dragonflight both wanting it personally, but with how close the two races are, and how amicable they have been I could see it being either left at the Temple of Elune, or placed somewhere important to Ysera, with easy access made to it for any would be Kaldorei pilgrims.
In any case, the Pillars of Creation all have incredible relevance to the peoples that had them before, and with them no longer evidently being needed to protect Azeroth (since the theft of the Tidestone didn’t cause any catastrophic harm to Azeroth) I would very much see these people requesting them back.
Though I’d be interested to hear cases to the contrary.
