Thadrea is a highland surrounded by the foggy Ashmond Mountains and situated on Gordean, the southern continent of Auratia. The dominant power in this region is the Norden Kingdom, which was founded long ago by the Tunno people, a race as influential as the Osira in Auratian history. While Osirans developed a combat style based on their command of weaponry, the Tunnos specialized in complex and powerful magic.
