Take the portal to Stormwind in the Sanctum of the Sages and meet with Ambassador Moorgard in the Stormwind Embassy.
Thank you for meeting with me, <name>.
I need representatives to go to Stormwind to represent our loyalty and commitment to our newly forged bond with the Alliance.
I've had Yvia and her magi prepare a portal to the city for you in the Sanctum of the Sages. Once there, go to the Stormwind Embassy and meet with Ambassador Moorgard.
You will face many challenges on the long journey ahead. Remember where you came from and make your people proud!
