This quest was marked obsolete by Blizzard and cannot be obtained or completed.
Using the Beacon Torch, mark each tower in Andorhal; you will need to stand in the doorway of the tower to successfully mark it.
Once all four towers are marked, return the Beacon Torch to High Executor Derrington at the Bulwark, Western Plaguelands.
Through the use of a magical device known as a beacon torch, we can mark targets of our choosing for future actions by our troops. To that end, we think the Scourge are using Andorhal's watchtowers as a means to control their troop movements.
Your mission: breach Andorhal's defenses to plant beacons at all four watchtowers. You'll need to be in the doorway of each tower to plant the beacon; it will then proceed to mark the tower. There are only five charges on the beacon torch, so use them wisely!
My warlocks are reporting that our beacon trackers are picking up extremely strong signals on all four towers! You've executed my orders with the skill and precision of a seasoned veteran. Your service to the Horde is duly noted once more, <name>!
With the towers marked, our preparations for the attack are now in place. The time has come to take the fight to the Scourge!
