Blackwing Lair Instance will be the next major content patch to be released, followed by Zul’Gurub. World of Warcraft UK Website has released a preview of what to expect in Blackwing Lair and a few screenshots. The instance will be inside Upper Blackrock Spire, on the opposite side of the hall leading to the Beast area. Nefarian—known as Blackwing, is son of Deathwing and brother of Onyxia. Caydiem confirmed that Blackwing Lair will be more difficult than Molten Core. No doubt a great challenge for hardcore guilds. Read the full preview at Wow-Europe.
