Golarion
Golarion contains eight continents amid its immense seas. The largest of these is Casmaron, which spans much of the world's northern hemisphere. On its western edge, bordered by the World's Edge Mountains, Casmaron expands into a large peninsular continent called Avistan which plays host to a number of civilizations built upon the ruins of great past empires, such as that of the Thassilonians.
Southwest of Avistan, across the Inner Sea is the largely unexplored wilderness of Garund. Whether one is scouring its northern deserts for lost relics of the Osiriani pharaohs or trekking through the near-impenetrable jungles of the Mwangi Expanse, Garund provides endless adventures for those willing to risk its many dangers.
A thousand miles to the west from the Arch of Aroden are the remnants of the once great island-continent of Azlant, which saw the rise of the first human civilizations. All that remains of Azlant today is a series of jutting crags and narrow, twisted channels; most of the continent sunk beneath the sea when the Starstone fell from the sky.
Past the treacherous obstacles of Azlant lies the expanse of the Arcadian Ocean and the lush island continent of Arcadia which gives the body of water its name. 4,000 miles from the shores of Avistan, little is known of this land but in the most ancient of texts and lore from long-fallen empires, though there are infrequent trade and colonization efforts from Avistan to Arcadia.
The smallest continent on Golarion is Sarusan, which lies amid the least traveled portions of the sea.
An immense frozen desert spans the northern pole of the planet, called the Crown of the World.
While much too cold and harsh-weathered for permanent and successful habitation, the Crown is most often traveled as a means of reaching the far-eastern continent of Tian Xia on the opposite of the world from Avistan.
