HOW THE KNOWN UNIVERSE WORKS
This article is to serve as an explainer into how and why the Celestial Bodies—planet-stars, star-planets, continemos, and other Omneuttian bodies—are composed and organized.
Celestial bodies in In Extremis’ universe of Omneutta are slightly different from what you are used to seeing from stars and planets in Earth’s solar system. Omneuttian celestial bodies are modeled after terrestrial planets like Earth or Mars. However, instead of continents that rest on a semi-solid mantle, the continents float through space around a star-core. This also means that Omneuttian celestial bodies do not have large oceans. The cutaway diagram (seen right) illustrates how Celestial Bodies in Omneutta are made up: with continents or landmasses in tight, synchronous orbit around a star-core.
Star-Planets take the place of stars in Omneuttia and generate light far enough to be seen far across the sky, whether night or day. The star-core inside star-planets is much larger and closer to the landmasses that orbit around it. Because of this, star-planets are uninhabitable to mortals.
Planet-Stars are the other major bodies of Omneutta. They can be found in orbit around Star-Planets or on their own (see Planemos below). The star-cores of these are smaller and as a result the Sentient Species along with other Omneuttian flora and fauna have flourished. Some star-cores among Planet-Stars are larger or smaller than others, leading to differences in average temperatures between planet-stars.
Planet-Stars that are not in orbit around a star-planet are referred to as Planemos, planets that do not orbit a larger object. Some planemos in Omneuttia have developed binary or multiple orbits with other planemos.
Continemos are continents or landmasses that do not orbit a star-core. Due to the lack of heat they usually feature cold and harsh locales. If formed from a dense enough material, the change in gravity from a planet-star’s landmass may not be noticeable.
