Alert The Warchief

You have successfully defended Orgrimmar from the threat posed by this Twilight's Hammer cult,<Name>,and without shedding the blood of our own people. Our enemy will not rest for long. I cannot imagine that Cho'Gall will accept defeat so easily. You must take word to Thrall. Go to the Valley of Wisdom and speak to him in Grommash Hold. Tell the warchief that our enemies have shown themselves and we must be prepared for their return.
