The skeletal remains of a sea turtle lie in the sand of the northern Darkshore beaches. The Greymist murlocs have either not found this carcass, or perhaps they have and are shying away from it for some unknown reason. Regardless, there is enough of the turtle left to take a sample back to Gwennyth Bly'Leggonde in Auberdine for the Temple of the Moon to study.
You've found even more beached creatures, <name>? Sea turtles were commonly found frolicking along the base of Nordrassil before it was destroyed. With the birth of Teldrassil, however, these creatures have been seen in ever decreasing numbers. Some, as we have discovered, end their lives here for some unknown reason.
Your aid will perhaps unlock the mystery before us. Please accept this in exchange for the remains you have provided for our study.
