Palusia is a distant planet endowed with the gift of life, but not its own, rather seeded by some civilization. Who made it is unknown at this time, but the most obvious, and at the same time likely, is that it was the species Homo sapiens sapiens, since these organisms are native to their planet. The reason for this is still unknown, but it could have been a mere experiment, an abandoned tourist resort, or a transportation error.
The planet has an average diameter of 11,000 km, with an axial rotation of -20°, which has generated a warmer northern hemisphere than the southern. Its average temperature is 21° Celsius, slightly less in the coldest areas of the planet. As Palusia has a fairly pronounced greenhouse effect, along with high humidity, which retains heat and has spread forests and wetlands throughout the planet. Due to the scarce presence of strictly terrestrial trees on the planet, most ecosystems are composed of mangroves, swamp cypresses, and, to a lesser extent, myrtle trees, almost exclusive to the planet's forests. This has led to biomes such as jungles being composed of numerous streams and extremely soft soils, sometimes just beeing stagnant water. On the other hand, areas less dependent on trees, such as grasslands or steppes, are found more in the centers of continents. Here, due to the lack of necessary moisture, trees would barely grow, giving way to vast plains with harder soil, with the drier areas forming vast steppes. Finally, the tundras and taigas would be composed almost exclusively of mosses and ferns, even the taigas with occasional trees, where much of the limited fauna that can survive in these ecosystems would be concentrated.
