Huarinrinerk stumbled upon an old temple in the Mist Valley, which might well contain treasure. However, she was not able to search for any treasure because of the Pretor Scouts and Black Armour Kirrins around the temple, as well as a huge rock blocking the temple entrance. You agreed to remove the obstacles. You removed the rock, Pretors, and Kirrins and came back to receive a much smaller reward than expected.
