How to find SITE 6 for Gjallarhorn Year 3 Quest
Site 6 is a well hidden location in the main building of Archon’s Keep. Enter it and go the public event area called Archon’s Forge. Just behind the first bubble is a small door that leads you to Site 6.
Follow the way through some tunnels until you get to the laser gate. Use your Splicer Key here that you get from Wizards in the Plaguelands.
The Iron Medallion for the Gjallarhorn Exotic Quest can be found just left of the laser door.
