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.
