According to evidence from radiometric dating and other sources, Fantasia was formed about 5.85 billion years ago. Within its first two 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 blocks the most life-threatening parts of the Sola's radiation, enabling life to flourish on land as well as in water. Since then, the combination of Fantasia's distance from Sola, its physical properties and its geological history have allowed life to thrive and evolve.
Fantasia's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. Fifty-two percent of Fantasia'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. Fantasia's polar regions are covered with thick ice sheets and the sea ice of the polar ice packs. Fantasia's interior remains active with a solid iron inner core, a liquid outer core that generates the magnetic field, and a convecting mantle that drives plate tectonics.
