Ok, so this is a picture I took of when you talk to Wrathion about starting the Legendary quest line.
This was my third time doing this & I paid a bit more attention to the details.
Those green meteors remind me of the ones the Legion uses & that do fall down on Honor Hold.
Chris Metzen even said that Alleria & Turalyon would be needing our help in the future when a player asked him a question about them during the Pre-MoP launch party in CA.
Last known where about of those two that I know of is the Twisting Nether.
