Deep within the Rantha mountains, located in the Land of Dawn sits an ancient fortress. Though the owner is unknown, it is rumored that it could be a descendant of the legendary race of Earthen Giants, that once walked the Lands of Dawn. It said that this race is older than the earth itself, having a special affinity for nature, they were able to build deep connections and relations with various beings of nature, especially the Stone Titans. These amiable giants possess rocky skin that is almost impervious to all physical force. Due to their kind nature, they mainly use their physical prowess to keep them away from other creatures and sleep safely. These stony giants love sleeping so much, that they have the ability to hibernate for up to half a dozen years sometimes. As they sleep, it is natural for trees to be grown within their skin and even buildings to be constructed on them. However once they are awakened, it is hard for them to fall asleep again. One day when Grock, one of the strongest of these Stone Titans, awoke, and found himself to be alone, the guardians of the fortress long gone. He proceeded to saddle the fortress onto his back to find the owners, setting out all over the Land of Dawn to find any news on their whereabouts, so he may one day return their home to them.
