This quest is not available in game.
Bring a Wild Leather Vest and a Wild Leather Helmet to Caryssia Moonhunter in Feralas.
Completing this quest will give you access to the Tribal Leatherworking arts.
The completion of this quest will prevent you from learning Dragonscale Leatherworking and Elemental Leatherworking; be sure this is the path you wish to follow before doing so.
To learn tribal leatherworking demands an understanding of how primal nature truly is; I know that you have already mastered the art of making wild leather armor, and I am willing to complete your training.
Know this, <class>: by choosing this path you agree never to learn dragonscale or elemental leatherworking; there is only room for practice of one of the three arts. Furthermore, bring to me the finest samples of your wild leather armor. From there, we will begin your mastery.
