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!
