I have seen a topic such as this but it was quite old, so with the legion and shadowlands I felt like it is a question that must be asked.
While I realized that Sisterhood of Elune is strictly kaldorei based (and mostly female). From what I read druids of the moon also harness Elune’s power, and they do have worgens in their ranks as well, they also inhabbit the temple of the moon as well.
Apart from that worgens themselves are also tied to Elune to a degree, main reason why they are harder to raise is that they are tied to both emerald dream via Goldrinn and Elune’s magic.
Thirdly with Shadowlands we now know that there are practicioners and followers of Elune throughout the cosmos, even night warriors, who are not night elves.
So what do you think, can a worgen follow Elune or harness her powers?
