Kaladay is a kingdom of Casmaron, to the east of the Castrovin Sea. It is said to consist of arid plains and fabulous cities. It was settled by xenophobic colonists from Tian Xia and the realm is largely unvisited by people from the Inner Sea.
One such visitor may have been Truan Iolavai. The Record of Truan Iolavai details his journey from Oppara in Taldor to the Kaladay province of Yen-Shuan. Of course, many historians doubt the accuracy of large parts of the Record.
