This is basically the closest I'll ever get to Illidan.
Once you reach Exalted with the Netherwing, you get a quest to meet Illidan himself. Well, an image of him, anyway. He of course sees right through your simple disguise and is about to zap you, but you're rescued by a nearby dragon-in-disguise (Yarzil the goblin, on the far left) who flies you AT RUNNING SPEED all the way across Shadowmoon, across Terokkar, into Shattrath. Takes about 15 minutes, and nothing happens during that time. Awesome quest, but the flight needs work.
