Can now be purchased for 200 Tol Barad Commendations from Quartermaster Brazie (Alliance)

I thought I would go for a wander into the crater for a look, armed with the coords for the nests and a mud map of the locations to make it a little easier. No sign of the Matriarch, but there at the first location, a nest, ok, don't get excited now, could be nothing, but wait, it was clickable, AWESOME! How can this be. On the other hand, about flaming time I found a rare spawn with no trouble. About 9:40am. Nagrand. Nest next to tree at approx. 69 67.
Good luck.
