Druxus Rhym, an important Red Wizard of Thay created only a few of these spectacular rings. His allies among the tharchions and zulkiers have earned theirs by helping Druxus amass even greater power than before. A few others have been used to bribe ruling lords, who were attempting to stop the growth of the Thayvian enclaves. Some mages have speculated whether Druxus might have some darker purpose in distributing these rings, but so far, no proof has been offered.
