East of the World’s Edge Mountains spans the largest of Golarion’s land masses, the sprawling super-continent of Casmaron. Traders seeking the exotic markets of the east venture along the Golden Path, an informal trade route leading from Qadira’s capital in Katheer through the hostile central steppes and deserts of Casmaron to the heartland of Imperial Kelesh. From there, the route ventures through the storied Impossible Kingdoms of Vudra, land of 10,000 gods and a 100,000 miracles, a realm so fantastic and sublime that the stories told by those who claim to have traveled there must surely be lies. Both Kelesh and Vudra claim immense regions as their own, rivaling the height of Avistan’s moribund empires of Taldor and Cheliax, but they are hardly the only powers of vaunted Casmaron. In the distant north, among foreboding pine forests rivaling the primeval Arthfell, the stalwart remnants of the stricken kingdom of Iobaria fight desperately against the barbarism engulfing the nation’s collapsed colony states.
The vast, landlocked Castrovin Sea stares from the center of Casmaron like an unwinking eye, lapping against the forlorn shores of Iobaria in the north; the forgotten cities of ancient kingdoms like Ninshabur, Kaskkari, and Iblydos in the west; and mighty Kelesh in the south. The Castrovin’s distant eastern shore touches the western reaches of the legendary land of Kaladay, a xenophobic realm of fabulous cities and arid plains inhabited by colonists from Tian Xia in ancient times but little visited by the folk of the Inner Sea. So remote is the land of Kaladay that only the most learned scholars of the Inner Sea are aware that it exists, and only a handful of living explorers can reliably claim to have visited there.
