Considerably larger than they appear
As planets are not defined by single continents—unless they are supercontinents, single plains of reality, or else abnormally large landmasses—here would be the second half of the map posted earlier, on the opposite half of the planet.
To the far east are the more broken-up continuations of Fosburg, or the Cards, called the Cutters. They are ragged lands, cooler than the Cards but lacking the winds or forests that brought humanity to settle in the latter. Religious zealots are exiled here sometimes from Verdegris.
Closer east, arranged together, is the Circle: a meteoric crater that formed into a sea when the rains flooded the world. The eastern subcontinents and western coastlands reap the benefits of nutrient-rich muds kicked up by the waters, and have the small city-states of Shir, Drah, Albin, and Mara that have some mixing and trade.
The northern section of the central continent is Slow Country, a sort of mixed scrub- and grassland with mountains to the southeast and islands to the northwest. Lack of rivers makes this land unpleasant and unpopular for civilization, but the dried lake-beds yield up valuable potassium salts to fuel the emerging shot-powder industry and interested chemists. Long-legged canids with tremendously long tails hunt in packs here, and massive grey-skinned quadrupeds wander with teeth bared.
The southern section of the central continent is Dead Country, hot and wretched grasslands with life only under the stone and soil. Semi-underground communities reside here, farming mushrooms and fungus, killing off outsides and lost wanderers.
South of Dead Country is Polewaters, home to a somewhat xenophobic monarchy with several warring dynasties and an ever-shallower genetic pool. The capital city, has been rebuilt at least seven times, and sacked many more. Most of the working population is capable with militaristic endeavors, and mercenary companies are hired very often. Winter on this subcontinent is mild, but freezes quite a lot of the surrounding sea as well, preventing trade or import.
East of Dead and Slow Countries is the subcontinent of Stagger, the last landscape before the great ocean that separates the two halves of the planet. As such, prophets of the end gather there to watch the endless roiling seas and make predictions based on cloud formations and bird entrails. The descendants of those myriad ancient followers and disciples have formed multiple small villages spread out across the coast and taken up supportive lives for the prophets, even with no end-times having occurred in many centuries.
