The Soulgiven was a group of people so strong that they should be preserved for later use when the land needed them. So they took a part of theire soul and preserved it in stone. So the Soulgiven were locked in time as statues until the time they were needed. that time never happened, because the civilization that made the Soulgiven perished. Then after hundred or thousands of years later they were brought to life by a few adventurers. So the Soulgiven were locked in time as statues This unfortunatly had some side effects, like a weakness to be turned to stone again.
