Erdea is the closest planet to the star Sol, and the only habitable terrestrial planet in the solar system. It has a dense atmosphere with Earth-like conditions and has surface features reminiscent of the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Erdea are likewise similar to those of Earth, as is the tilt that produces the seasons.
Erdea’s lithosphere is divided into several rigid segments, or tectonic plates, that migrate across the surface. About 2/3 of the surface is covered by salt water oceans, with the remainder consisting of continents and islands which together have many lakes and other sources of water that contribute to the hydrosphere. Erdea’s poles are mostly covered with ice. The planet’s interior remains active, with extremely dense solid inner core, a liquid outer core that generates the magnetic field, and a thick layer of relatively solid mantle.
Erdea has surface gravity around 1G. Its rotation and orbit are roughly similar to earths, resulting in a 24 hour day and a 360 day year. It is orbited by two satellites, Kuu and Pienku. Kuu is much larger, roughly 1/4 the diameter of Erdea. It is tidally locked, and goes through its orbit of the planet every 30 days. Pienku is 1/4 the size of Kuu, and its effect on the planet is much smaller. It also orbits at a much faster pace, completing an orbit every 14 days.
There are two major continents on Erdea, and several large island complexes that are also inhabited by the modern races.
- The Great North Continent is the largest landmass on Erdea, reaching up into the north pole at its top and extending well into the southern hemisphere. It dominates the western hemisphere of the planet. It’s equatorial region contains the largest desert on the planet, the Great White Wastes of Nephria. The continent also contains the nations of Inling, Lias, Turuk, Druin,Hannede, and Maraph.
- Xish is the second largest continent, and the largest of the eastern hemisphere. It is mainly contained in the southern hemisphere. It is an extremely magically active continent, with strange areas where magic functions differently, or has affected the land in ways not seen in any other place on Erdea. It is ruled in it’s entirety by the Xian empire, an exotic kingdom until recently led by the sorceress Daresh in the capital of Dareshtan. With her recent death, the throne is up for grabs it seems, and political machinations within the noble house of the Xian are in full motion.
- Aria is an island continent, 1/4 the size of the North Continent and far to the east of it. It is now inhabited by peaceful refugees and defectors from the Elfwar.
- Kaerlendra is a tropical paradise near the equator. It is a volcanic island chain ruled by a unique matriarchal society. It lies between Aria and the North Continent.
