Scales of War
Thandor is an area on the west side of the continent. It was one of the three great kingdoms of ancient times. When the Boundary appeared 1,000 years ago, the kingdom was thrown into chaos. Several cults gained power and rose to prominence by blaming the Boundary on the secretive wizards employed by the monarchy. This eventually resulted in a series of uprisings in which all types of arcane magic users were exiled or killed, with even many priests, druids, and others being killed in the wave of violence. This period is sometimes referred to as The Cleansing.
In current times, some still tell tales of Throne City, the shining seat of power of the old kingdom of Thandor. However, real knowledge of anything prior to The Cleansing in Thandor is extremely rare.
