Here are a few links for the Nefarian fight in BWD
Guild needs 8 to 10 guild members on this fight to win it and get a guild achievement. (EDIT - We downed it - guild got the cheevo!! leaving this up for the personal achievement seekers among us though.)
That achievement would allow all guild members (with proper rep) to buy the Dark Phoenix Mount!
We will keep trying to kill this guy until we get him - might as well get your leet character ready by watching these videos and help us!!
