Cragmaw Castle was located in Neverwinter Wood. It was originally built by the dwarves of Stonehill Mountains under the tutelage of the First Mage of Neverwinter Woods. The Mages were an elected line of succession in the early ages. There were a total of 11 in all. the final Mage was Thul who converted to the black arts and following his assassination the castle was abandoned.
Many years later, with the castles a mere ruin, the Cragmaws moved in. These were a mixture of goblins, hobgoblins and bugbears. Their most famous leader was King Grol
