The home of the watchelf.
This stone has been the home of the watchelf for thousands of years. It has view of the Esja, the mountain overlooking Reykjavik. Iceland has 13 Santas and their mother is a evil troll that eats children and every time she goes prowling the watchelf warns the people of Iceland by lighting up the sky with green lights that people call northern lights. The fuel for the northern lights are treats geocachers leave behind. So bring some nick nacks to leave/swap.
