Siora
Lua error: Internal error: The interpreter exited with status 127. Siora, often called the world in common usage, or Midlost (especially in fantasy fiction), is the third planet from Sol, the densest planet in the Sol System, and one of two astronomical objects known to accommodate life. Siora's biodiversity has evolved over several hundred million years, expanding continually except when interrupted by mass extinctions. Although it's estimated that over 99% of all species are extinct, Siora is currently home to 10-15 million species, including several billion humans.
According to evidence from radiometric dating and other sources, Siora was formed around four 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 layer ozone layer. This layer and the geomagnetic field block the most life-threatening parts of the sun's radiation, so life was able to flourish on land as well as in water. Since then, the combination of Siora's distance from the Sun, its physical properties, and its geological history have allowed life to persist.
Siora's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. Siora'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.
Siora gravitationally interacts with other objects in space, especially the sun and Luna. During one orbit around the Sun, Siora rotates about its own axis 392 times, creating 392 solar days, or one sidereal year. Luna is Siora's only natural satellite and began orbiting the planet about 3.5 billion years ago. Its gravitational interaction with Siora stimulates ocean tides, stabilizes the axial tilt, and gradually slows the planet's rotation.
Etymology
The modern Lanlian Siöra Template:OOC developed from Middle Lanlian Siore, the term for: the ground, soil, dry land, and the globe. Siore was a personified goddess in Lanlanian paganism. While Siore was considered the embodiment of the world as a whole, Midlost was the personification of the "human world".
