All the mobs listed here form the video are not part of the Utgarde Catacombs instance. The video is of the pre-instance area of the keep, not any of the instances. -- Zeal (T/C) 06:37, 28 May 2008 (UTC)
Also see Talk:Utgarde Keep#Catacombs. The instance info of this article needs to be merged into the main one. -- Zeal (T/C) 08:12, 29 May 2008 (UTC)
