The Shrine of Korth

Loot the dead darkspawn laying by the golem. You will recieve a golden idol. There is also a book that will give you a codex about Korth. If you add the golden idol to the offering it will claim you have opened a hidden compartment. Automatically added to your inventory is the 2-handed axe Frenzy. If you take the offering (15 gold) the 2 guardian golems will attack. They are easy to kill but offer no good loots.
