The landmasses listed below are ordered by rough size (and usually, but not always, importance).
Region: Yandjee
Area: 7,724,090 kmˆ2
Hot and dry, a touch larger than Australia, Yandjee is by far the largest landmass on Tjarral…and one of the least habitable, with much of the interior given over to the Barranur, the Red Sea of sand. Still, there is enough jungle, rich delta land, tall forest, and sunny shoreline to support a reasonable population of around 28.6 million people (a mere 3.7 people per square kilometre, but it's not insubtantial).
Region: Mocueyoh
Area: 3,587,400 kmˆ2
Still warm, less dry, a fair bit larger than India, Mocueyoh is the second-biggest landmass on the planet, stretching from tropical rainforest and monsoon plateaus in the south to chilly humid continental and temperate rainforest climates in the north. Across the whole dwarf continent, the population is around 132.7 million people—37 per square kilometre.
Region: Oma
Area: 3,058,277 kmˆ2
Cool to cold, only slightly larger than India, Hetrisia is divided into two broad regions: the temperate peninsula of Einir, and the frozen icecaps and tundra of Sinyi. It's worth noting that for this reason, the population, which is a full 21 million people, is in fact quite concentrated on Einir (otherwise the population density of the whole dwarf continent would be just about 7.9 per square kilometre); it's also worth noting that about three thousand people live in the Bay of Palena on the opposite side of the dwarf continent, and another 50 thousand in the icy reaches of the tundra and the Nagh (the high mountain range between Einir and Sinyi).
Region: Oma
Area: 1,199,538 kmˆ2
A little bigger than Ethiopia, Aion is mostly given over to rugged coasts and valleys bordered by tall mountains. In the west, the climate is practically mediterranean; in the east, it becomes drier, turning to steppe intersected by rivers from the great mountain ranges. It has a total population of around 19.2 million (16 per square kilometre); of these, over a third live in the cities of the Phaeroi.
Region: Sayintha
Area: 821,440 kmˆ2
Slightly smaller than Namibia, Pumirna is an island set between two broad climate zones—a tropical mountain range with a climate like Ecuador's in the south, and mixed jungle and grasslands in the large northern "triangle". The population is around 39 million (48 people per square kilometre), with a small majority living along the southern mountains in the cities of Durnhão.
Region: Sayintha
Area: 568,501 kmˆ2
A touch smaller than Kenya, Verna is highly monsoonal—dry enough during the summer months (thanks to the mountains in the west), but right in the middle of the intertropical convergence zone during the winter. It is here that agriculture first arose in the Sayintha region; today the island sports a population of 48 million people (about 84 per square kilometre), most of which is either urban or agricultural.
Region: Sayintha
Area: 386,940 kmˆ2
A tiny bit bigger than Zimbabwe, the tropical island of Inakku sits between the dwarf continent of Mocueyoh and the wider archipelago of Sayintha. It has a population of 10 million people (19 per square kilometre).
Region: Sayintha
Area: 268,701 kmˆ2
Around the size of New Zealand, Qomētti (also called Nawakano) sits between Inakku and Svidhuni, and shares with them the spectacular forests of the region while also being home to a unique group of primates, the lemurs. Its human population is spread out at about 7 per square kilometre, for a total of 1.8 million.
Region: Malehi
Area: 225,187 kmˆ2
A little smaller than Ghana, Onuhi is the more southerly (and thus colder) main island of Tehapu. It has a population of 439 thousand people (around 1.9 per square kilometre); much of the interior is given over to wilderness.
Region: Sayintha
Area: 109,246 kmˆ2
Slightly larger than Bulgaria, the island of Kshekara sits just off the stormy southeastern coast of Svidhuni. Kshekara's flora and fauna are somewhat unique for the rest of the planet, something that millennia of interchange has been unable to quell. It is home to 1.4 million people (with a density of 13 per square kilometre).
Region: Oma
Area: 96,640 kmˆ2
A little smaller than South Korea, Knausor is relatively temperate; it was here that agriculture first arose in the region. The average population density is about 32 per square kilometre, leading to quite a crowded island at 3 million people.
Region: Malehi
Area: 70,372 kmˆ2
A little larger than the country of Georgia, Tinao is the more northerly—and more temperate—of the two islands of Tehapu. With a population density of 12 per square kilometre, the island boasts 844 thousand inhabitants—about two-thirds of the region's total.
Region: Sayintha
Area: 50,264 kmˆ2
A little smaller than Costa Rica, Corundalha is hilly and tropical, with most of the settlement along the coast (the jungle interior is as of the present day still largely "untouched" by modern civilization). The average density is around 15 people per square kilometre, making for a total population of 754 thousand people.
Region: Malehi
Area: 31,849 kmˆ2
A touch smaller than Taiwan, Eiua is the largest and chief island of the Akulihan archipelago. Tropical and mildly volcanic, Eiua is one of the remnants of a fallen continent that once occupied this area of the ocean, and is thus home to some quite unique forms of life. With a population density of 36 per square kilometre, even without the other islands it adds 1.1 million people to the population of Akuliha.
Region: Sayintha
Area: 30,280 kmˆ2
Around the same size as Belgium, Jhupra is tropical and fairly flat, given over to thick jungle (its name means something akin to "rainforest" in Kshamakaraktha). Most of the inland is untouched, the settlements clustered around the coastlines and the main rivers; despite this, the population is around 3.1 million people (about 102 per square kilometre).
