Liliaplatias (IPA: /li.lia.plæ.tias/), translated as infinite land or infinite planet, is an infinitely-large land that spans an entire universe. It is like a planet with infinite radius, but its gravity is Earth-like and its horizon stretches out forever. There is an extremely large area lush in flora and fauna, which has been slowly spreading out ever since the beginning of life; this is called the "biosphere". A smaller region, called the "ecumene", is occupied by human civilizations and that of other sapient races.
Liliaplatias' lithosphere, which is very deep, is rich in minerals and metals and contains large caves in which subterranean civilizations often occupy. Tectonic plates exist, but they are much less active compared to Earth's. As Liliaplatias' depth is infinite, it has yet to be ascertained the nature of the core, or if there is, in fact a planetary core.
Infinite suns travel across Liliaplatias, all in a grid pattern and in one direction. They vary periodically in intensity and height, creating the effect of seasons. They are spaced far enough that there is a day/night cycle, and biomes from arctic to tropical are created depending on the latitudinal distance from the local suns. The Liliaplatian day/night cycle is exactly 24 hours long, and the year, judged as the passage of spring, summer, autumn, and winter, is exactly 360 days long.
The continents are subjected to less erosion and change due to the fact that Liliaplatias has no spherical shape, and thus, pressure systems do not spill over and affect the same area, reducing wind erosion. Global warming is affected in the same vein, with more air for the pollution to spread through, smog is encountered in less deadly amounts, because of this, regions with polar climates do not succumb to global warming, and the subsequent melting of regional ice caps.
Liliaplatias' night sky is visibly dotted with points of light, which resemble stars in other universes, but they are thought to be infinitely far away.
