Buy a wind rider to Orgrimmar from the wind rider master Devrak, then bring Zargh's Meats to Gryshka in Orgrimmar.
For just a few coins I will have a wind rider bring you to Orgrimmar. When you get there, you can take Zargh's Meats to Gryshka. Her inn is in the Valley of Strength, not far from the Skytower, where my wind rider will drop you off.
Speak with me again when you are ready for the journey.
