The remains of a giant thresher - much larger than one you'd expect to find in Darkshore - lie beached on the coast of the Mist's Edge. How this creature came to be here is unknown; the group of murlocs that now feast off the carcass of it seem to be much too weak, even in large numbers, to have brought down the beast.
While some of it has been picked clean, enough of it remains to take a sample for Gwennyth Bly'Leggonde in Auberdine to study.
Another discovery - well done <name>! These remains will be properly studied once they get to Darnassus. Please accept this small honorarium in exchange for the remains you have provided for our study.
