Speak with Rexxar at Thunderlord Stronghold in the Blade's Edge Mountains.
<name>, now that you can see me, there is something you must tell Rexxar. I know that he seeks his people, and I know where they are.
The Mok'Nathal, as they are known, have a village to the east beyond the Razor Ridge.
Go, give Rexxar this news. His people are in danger, and I know that he will want to come to their aid.
