Provided: 
Pratt's Letter
Description
Well adventurer, you are the definition of diligence. There is one pattern left for Wild Leather armor; you've mastered the others. I won't require you to toil needlessly for the pattern. You've earned it outright, and then some... but I cannot give it to you myself. My teacher, the one who brought me into the craft, is the one who must reward you.
Take this letter to Telonis; he teaches leatherworking in Darnassus. Show him the letter, and let him acknowledge you as an equal, as I do.
Progress
Greetings, friend... from your countenance I can tell you are a leatherworker as am I. Have you come to draw from my skills, or perhaps you have other business with me?
Completion
Ah yes, Pratt sent you. Though he is a human, he reminds me of us night elves sometimes. His dedication and his talents with leather are impressive. For him to compliment you so in this letter, it is a sign of respect I acknowledge.
I am aware that he has taught you the art of Wild Leather. Allow me to finish your training with this pattern. Make good use of it; few in the world know the secrets of Wild Leather cloaks.
