Nightbane, the undead dragon in Karazhan. The fight is very intense and for some, considered the hardest of them all. We had the pleasure of taking him down tonight as a guild. Thanks to everybody for fighting so hard, it was indeed a tough fight. We learned it and manged to do it! Yay! Afraid I forgot to show the names of the guild members there, but you know who you are :-) (or write a small comment with your name below the screenshot :-)
