Speak with your faction leader in your garrison and complete the quests to build a shipyard. Khadgar will meet you there when it's built.
Our campaign in Draenor has taken an unexpected turn. With Gul'dan assuming power over the Iron Horde, history is poised to repeat itself - our world is in more peril than ever.
It's time to bring the full might of your garrison to bear against Tanaan Jungle. Build a shipyard for your garrison! I will meet you at your new shipyard and we will discuss our next move from there.
