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. Looming above the face of the necropolis is the all-seeing eye of Acherus. From it the master is able to see great distances into the territories held by our enemies. What the eye sees, the Lich King sees, and now the time has come for you to peer through the eye! The Lich King has called for you, <name>.
Go now! Suffer well, <brother/sister>...
The time to spill the blood of our enemies approaches. You must first learn what it is that you seek to destroy, before rushing headlong into battle. It is what separates a death knight from a mindless ghoul.
I will grant you sight beyond sight, my champion. You will use the eye of Acherus to gather information on our agents.
