Corp'rethar, called the Horror Gate. It is the last barrier between us and the Icecrown Citadel. It waits to the south of the Ironwall Rampart, beyond the glacier and The Conflagration. By the time our troops reach it, they will be exhausted and worse.

I hope your success at Corp'rethar will prove an omen of the battle ahead. The Lich King cannot sit idly by as we march to the very gates of his stronghold.
The quest mobs can be found all along the ramparts. Note that the Harbingers of Horror have a knockback that can knock you off the rampart if you are not careful. The Corp'rethar Guardians also have a Mortal Strike-like ability that can stack indefinitely, similar to Gluth.
