Report to Thrall at Grommash Hold in Orgrimmar.
The Warchief needs you, champion. Orgrimmar is in a state of martial law. All merchants and services have been shut down as the Warchief prepares for an unavoidable conflict.
I cannot tell you much more - not now. Not in this place.
The Warchief commands that our strongest champions report to his throne room. Go now, [player]! Take the portal back to Orgrimmar and seek out Thrall.
