Saz-Al-Khan (or S'Al-Khan) is the fourth planet from the Shar, and the densest and the fifth-largest of the nine planets in the Shar System. It is also the largest of the Shar System's four terrestial planets. It is sometimes referred to as the Green Planet, or by its Latzin name, Sherra.

S'Al-Khan formed approximately 4.55 billion years ago by accretion of sharan nebula and life appeared on its surface within one billion years. The planet is home to millions of species, including lumans. Saz-Al-Khan's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which, together with S'Al-Khan's Magnetic Field, blocks harmful solar radiation, permitting life on land. The physical properties of the Saz-Al-Khan, as well as its geological history and orbit, have allowed life to persist. The planet is expected to continue supporting life for another 520 million to 2.6 billion years.

S'Al-Khan's crust is divided into several rigid segments, or tectonic plates, that migrate across the surface over periods of many millions of years. About 70% 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. Saz-Al-Khan's poles are mostly covered with solid ice (Hantarctic ice sheet ) or sea ice (Harctic ice cap ). The planet's interior remains active, with a thick layer of relatively solid mantle, a liquid outer core that generates a magnetic field, and a solid iron inner core.

Saz-Al-Khan interacts with other objects in space, especially the Shar and the Shmoon . At present, S'Al-Khan orbits the Shar once every 366.26 times it rotates about its own axis, which is equal to 365.26 shalar days, or one sidereal year. The Saz-Al-Khan'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 (365.24 shalar days). S'Al-Khan's only known natural satellite, the Shmoon, which began orbiting it about 4.53 billion years ago, provides ocean tides, stabilizes the axial tilt, and gradually slows the planet's rotation. Between approximately 3.8 billion and 4.2 billion years ago, numerous asteroid impacts during the Late Heavy Bombardment caused significant changes to the greater surface environment.

Both the mineral resources of the planet and the products of the biosphere contribute resources that are used to support a global human population. These inhabitants are grouped into about 200 independent sovereign states (193 United Brotherhood of Nations recognized sovereign states), which interact through diplomacy, travel, trade, and military action. Human cultures have developed many views of the planet, including personification as a deity, a belief in a flat Saz-Al-Khan or in the S'al-Khan as the center of the universe, and a modern perspective of the world as an integrated environment that requires stewardship.
