The Lich Kel'Thuzad, last boss of the 40-man raid instance Naxxramas, was killed tonight for the first time anywhere by a European Horde guild: Nihilum. A big congrats to them for this huge accomplishment!

Let's hope the Burning Crusade expansion will bring us a lot of new challenges of the same quality as Naxxramas, which is truely the best endgame raiding instance that has ever been designed. I'm sure Blizzard will manage that, but in the meantime, most guilds still have a lot to do before they can kill Kel'Thuzad
