Okay in all seriousness, this, I have serious disagreements on. I think people really misunderstand how the Elune faith is supposed to work, and that is why so many people dont understand why this is such garbage.
It makes sense that people’s perception of religion is colored by the Abrahamic concepts that dominates the modern world. How could an all good, all benevolent god allow bad things to happen such as this? In that context, a crisis of faith is totally reasonable.
That doesn’t really apply here though. Elune isn’t the all powerful, all benevolent God we see in the three main Abrahamic faiths. A more pagan perspective is far more reasonable, and that is very important worldbuilding distinction when it comes gauging the Night Elves would respond to tragedy.
Though, Blizzard has not too well defined what all the Elunite faith entails or preaches, but I think we can make some assumptions given Elune’s real life influences to make a suitable head canon that makes sense. Those influences primarily being Hecate and Odin. I have talked about it at length before, but I will spare the long winded explanation of my headcanon for now.
And I understand we can’t really write off lore with head canon, and we need something more cemented in lore. I argue that we have pre-existing examples of the Kaldorei’s reaction to tragedy, and every time their faith has been emboldened, not weakened.
The Sundering we see them turn towards a Theocratic State in the wake of the collapse of their Empire. And in Warcraft 3, we see the Kaldorei willingly sacrifice their immortality can command over nature in the face of great adversity. The conviction that takes should not be understated.
In many ways, the cultural identity of the Kaldorei is defined by their religious conviction. A Crisis of Faith in the wake of tragedy is only the double down on the Kaldorei culture erasure that was the War of Thorns.
So I completely reject the idea that Undead Kaldorei would lose faith in Elune and turn their back on their own people. It is not something that would happen, and as far as I am concerned, it didn’t.
