The Icecrown Citadel is the final raid instance in Wrath of the Lich King, and its final boss is none other than Arthas Menethil, the Lich King himself!

Similarly to the Black Temple and Mount Hyjal, players will be assisted by a special raid-only faction: the Ashen Verdict. Teleportation devices placed in various points inside the Citadel will allow raiders to quickly move around the enormous building, and Alchemist Finklestein, Ashen Verdict Quartermaster, will aid in ensuring that player armor is always at its maximum durability.
