LOL, omg I admit I'm not in keeping with the lore as much as I would like, so I had to look up both Brightwing and the Emerald Dreamway, hahaha. I wonder if that was an idea that ended up on the cutting room floor at one point, because it would be so Blizzard to have a boss like that.
I missed so much of WoW. Started in Vanilla, quit at the end of Vanilla and didn't come back till MoP. Always wondered what became of the Dragons of Nightmare, so the EN raid gave me a sense of closure with them.
