The Blackthorne Pact. That's what they call themselves. Apostate druids that have taken over Hyjal Summit. Violent, and extremist. They blame Malfurion Stormrage for robbing them of their immortality, and have sworn to reclaim the power that they were forced to relinquish. I did not understand the magic that empowered them before, but it's becoming clear now. Take the staff, use it on the Blackthorne druids around the mountain. It should respond to and dispel the wards protecting them.
