What We Know

Our grunts found one of these Night Elves stalking about. The deformed creature had a letter on its corpse. I will spare you the disgust I had while trying to decipher that abomination of a language.

Above the canyon you should be able to find a Barrow Den, one of the holes these knife-eared mongrels like to dig. Be mindful not to go to the Dor'Danil Barrow Den: The one you seek is found in the ridge. From what I could gather of this piece of paper, a great menace can be found at its lowest level.

Find out what's hiding there and return to me as swift as the wind.

Hopefully you will survive to tell the story, <class>.

A Dreadlord of all things? This won't be easy, at your current state you're nothing more than a twig in a cyclone, but there are other ways.
