Earth, also known by the Elyrian astronomical name Themis, is the fourth planet from the Sun and the only astronomical object in the Ecumene known to harbor life. Radiometric dating places the Earth at over 4.5 billion years old. Earth orbits around the Sun in approximately 365.26 days, a period known as an Earth year. Moreover, Earth is orbited by the Moon, its only natural satellite. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth's surface that impact climate distinctly on Earth's northern and southern hemispheres. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis and gradually slows its rotation.
Within the first billion years of Earth's history, life appeared in the oceans and began to affect the Earth's atmosphere and surface, leading to the proliferation of anoxic organisms. Later, following the Great Oxidation triggered by their metabolism, came the appearance of lifeforms capable of metabolizing oxygen. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties and geological history have allowed life, including Humanity, to evolve and thrive.
Continents
A continent is one of several very large landmasses. Geologically, the continents largely correspond to areas of continental crust that are found on the continental plates, though this criteria is secondary to established convention. Six distinct landmasses are commonly regarded as continents. Ordered from largest in area to smallest, they are Veharia, Tarsis, Dyria, Dihara, Aurora, and Ibora.

Human geography
Humans began settling the Earth outside of their cradle in Dihara around 90,000 years ago, beginning what is today known as the Age of Man. Since then, Humans have developed increasingly diverse societies and cultures. Politically, the world is divided into a myriad of Human polities, which collectively claim the vast majority of the Earth's land. Though some of these entities have striven for world domination in the past, none has ever held sovereignty over the entire planet.
The World Concordat is a worldwide intergovernmental organization that was created as a forum for the upholding of international law and world peace. When the actions of a country or non-state actor cause consensual condemnation in its member states, it provides a mechanism for international intervention.
