The Halls of Reflection is the third and last wing of the Frozen Halls of Icecrown Citadel, released in patch 3.3. It was considered the hardest 5-man instance of the expansion, due to the difficulty and loot. The Halls of Reflection are the private chambers of the Lich King, the only place where he lets his guard down. Judging by the loading screen and map, it appears to be a dark, twisted replica of Lordaeron's imperial chamber.
