Speak with Orgnil Soulscar in Razor Hill.
We at Sen'jin Village are not without our own troubles, and we thank you for your aid. But the news you bring regarding the Burning Blade could be trouble for everyone.
There is an orc stationed at Razor Hill, Orgnil Soulscar, who polices Durotar from evils such as the Burning Blade! Go to Orgnil and tell him of our plight, as well as your news from the Valley of Trials. He will want to know these things.
