Speak to Neeru Fireblade in Orgrimmar.
I think our next step should be to have you placed close to Neeru. If he is as agitated as reports suggest, then we may accomplish two things. One, you may be able to gain some greater knowledge about the Council or at least the Burning Blade, and two, he may just begin to trust you enough that he asks you to start to aid him. He may very well look at you as someone who can fill the void now that some of the leadership is in turmoil.
Return to the Cleft and speak to him again, but do not be too overt.
