Bronze Doors
The Bronze Doors, located along the perimeter of the first level, block the seven passages which connect Yliakum to the Stone Labyrinths. They are normally open to allow access for the merchants, the only time when they might be closed would be when the survival of the Yliakum inhabitants might be at stake.
The Bronze Doors are all situated near some powerful energy source in order for it to provide energy to move the huge doors. The closest one the Hydlaa, the Eagle Bronze Doors, is powered by a water.
