You may speak with Tal the Wind Rider Master to travel there, or wait for the zeppelin.
Much has changed outside of Mulgore, <name>. The world is torn, and our Horde allies have turned down dark paths. We must guide them. Even in the darkest hour, we will bravely hold our heads high, and honor the Earth Mother in all we do.
You must go, <name>, and be this example. Go to Orgrimmar. Tell Warchief Hellscream how the Grimtotem were driven out. Let him know our pride and discipline, our strength and sorrow.
Tal at the Skytower will send you on your way. Go in peace, and never forget your people.
What makes you seek the Warchief of the Horde, tauren?
The Grimtotem forced from Mulgore... if Baine speaks for this, you are indeed a fierce warrior.
From this day, your strength is no longer your own. It belongs to me, and the Horde, as a weapon of War.
Hellscream's eyes are upon you, <name>. Victory or death!
Walk to the high tower in the middle and up to the top where Tal is. Talk to him to get a free ride to Orgrimmar.
Walk to the west where there's an elevator down, then move inside the big building in the center of Valley of Strength.
