Washed Ashore only requires a quick swim out to the skeletal sea turtle and back.
The Skeletal Sea Turtle is located at [32, 46].
That beached creature is not an isolated incident here in Darkshore. There are more along the coastline and even in the water. I would like for you to investigate another one that we know of; this one was reported to be in the water due west of Auberdine, close to a sunken vessel. Return to me with anything that you may recover that would aid our research.
Also, in your travels you may find other creatures. By all means, if you should discover anything then please bring it to our attention!
Once you have investigated the creature's remains in the water to the west of here, I should be able to file a proper report with the Temple of the Moon in Darnassus. Perhaps then we will be closer to discovering the reason why these unfortunate creatures choose to end their lives beached on the coast of Darkshore.
You've been a tremendous help here today; we now have a solid chance at unlocking the mystery of why these creatures choose to beach themselves on the coast of Darkshore. The idea that they might be fleeing the area around Teldrassil is disturbing. Should you come across others in your travels, please let me know. Our research here is but in its infancy.
On behalf of the Temple of the Moon, please accept this as thanks for the effort you have given. Thank you, <name>!
