Hadayan (pronounced HAH-dah-yan) is a small city in the Viridian province of Talliastu, located on the northern shores of Lake Han. Though today it is small and unassuming, Hadayan is believed to be the longest continually inhabited settlement in all of Thadria. Originally a cyclopean outpost, after the cyclops left or were driven out the ruins of their settlement were built upon by the human tribes of the region, who were in turn cast out by the arrival of the Viridian legions in the Y7600s. While the people who live in Hadayan have changed over the millennia, it has never been fully abandoned.
Modern Hadayan is home to many refugees, human and orc alike, from the conflicts in Hkarzda to the north.
