The half-devoured corpse of what might have been a giant sea mammal lies on the beach. A band of murlocs, stronger than those found closer to Auberdine, have taken up residence around the fallen creature. Enough of the creature remains that a suitable sample of its bones could be delivered to Gwennyth Bly'Leggonde in Auberdine.
The bones you have are from gentle sea mammals that are known to inhabit the waters surrounding the base of Teldrassil. They had never been known to violently beach themselves like the threshers had been known to. Why would these creatures do this, I wonder? Well, perhaps the study of their remains will bear the fruits of knowledge that we seek.
Again, thank you for your aid. Please accept this honorarium from the Temple of the Moon.
