Dominion Over Acherus

Behold, Acherus, the grand citadel of death! It has no equal in this world! Not even the mighty Naxxramas could withstand a direct assault from the Ebon Hold. Though your thoughts may still be hazy, we haven't a moment to spare. You must claim dominion over Acherus and your mind! The horns of war surge! Take the stairs on this floor - located north, south, east and west - to the garrison floor above us. Seek out Master Siegesmith Corvus and acquire his status report. It must be delivered to Thalanor.
