Today on the test realms for the long awaited patch 3.3 for World of Warcraft the third and last instance "Halls of Reflection" opened it's doors - letting you experience the epic quest line about the forces of Azeroth trying to get into the Icecrown Citadel and defeating the well known and notorious boss Arthas.
The german fansite buffed.de visited the instance and shows screenshots of the bosses and the rewards for finishing the epic quest line about the sword Quel'Delar. Also the site offers a video with scenes of the "Halls of Reflection".
