In order to obtain the last item needed to get into the Hall of Echoes, you have to head to the capital – Aleroth. The only way of transport is by a zeppelin, which you will find in the port. There are some barriers blocking your way that you have to disable. You can do it by the bunker M5(8). By using one of the special teleport you are able to move right next to the entrance. Take the ladder upstairs and clear the area.
