SECTION I: ADONIA

Adonia, also known as the World, ---, or ---, is the --- planet from the SOL, the densest planet in the SOL System, the --- of the SOL System's # terrestrial planets, and the only celestial body known to accommodate life. Adonia's biodiversity has evolved over hundreds of million years, expanding continually except when punctuated by mass extinctions. It is home to over eight million species. There are over # billion humans who depend upon its biosphere and minerals. Adonia's human population is divided among about # independent states that interact through diplomacy, conflict, travel, trade, and media.

According to evidence from sources such as radiometric dating, Adonia was formed around four and a half billion years ago. Within its first billion years, life appeared in its oceans and began to affect its atmosphere and surface, promoting the proliferation of aerobic as well as anaerobic organisms and causing the formation of the atmosphere's ozone layer. This layer and the geomagnetic field block the most life-threatening parts of the SOL's radiation, so life was able to flourish on land as well as in water. Since then, the combination of Adonia's distance from the SOL, its physical properties, and its geological history have allowed life to persist.

Adonia's lithosphere is divided into several rigid segments, or tectonic plates, that migrate across the surface over periods of many millions of years. # percent of Adonia's surface is covered with water, with the remainder consisting of continents and islands that together have many lakes and other sources of water that contribute to the hydrosphere. Adonia's poles are mostly covered with ice that includes the solid ice of the --- ice sheet and the sea ice of the polar ice packs. Adonia's interior remains active, with a solid iron inner core, a liquid outer core that generates the magnetic field, and a thick layer of relatively solid mantle.

Adonia gravitationally interacts with other objects in space, especially the SOL and the LUNA. During one orbit around the SOL, Adonia rotates about its own axis 366.# times, creating 365.# solar days, or one sidereal year. Adonia's axis of rotation is tilted 23.4° away from the perpendicular of its orbital plane, producing seasonal variations on the planet's surface with a period of one tropical year (365.# solar days). LUNA is Adonia's only natural satellite. It began orbiting Adonia about 4.53 billion years ago (bya). LUNA's gravitational interaction with Adonia stimulates ocean tides, stabilizes the axial tilt, and gradually slows the planet's rotation.
