Tizon is a rich world with a shirt-sleeve atmosphere and a balance of available surface water. The system supports a population in the 100's of millions, which makes it too urbanized to make an agricultural world. It is a member of Sword Worlds Confederation in the Sword Worlds Subsector of Spinward Marches Sector and in the Sword Worlds. This world supports a Sword Worlds Military Base and the system supports a Sword Worlds Naval Base.

Astrography & Planetology

Tizon is a member of the Spinward Main.

Tizon has two stars, the primary El Cid, and its companion Bucar. Tizon orbits at a distance of 2.0 AU. Tizon has two small moons, though neither have significant installations.

Tizon's primary is an evolving K2 IV star, which has become considerably brighter in the last 100 million years. Tizon was once uninhabitable, a Mars-like ball of rock that was well outside the system’s habitable zone; it only warmed as the primary brightened.

Mainworld Data

Tizon has two continents: the larger one, Treskaginir, covers most of the northern hemisphere, while a smaller one, Noeglen, takes up half of the south. The world is rich in minerals, with mining communities scattered all over the planet. Tizon's climate is chilly, so the population is concentrated near the equator, particularly around the Athskilinn Sea, a large inland sea that separates central Treskaginir from Noeglen.

Tizon has a dense oxygen-nitrogen atmosphere with almost perpetual cloud cover (only 10% of the planet receive direct sunlight at any given moment), resulting in a chilly climate. Tizon was subject to a fairly successful terraforming program by the Darrians before being abandoned in the wake of the Maghiz disaster. As such, Tizon actually supports some of the last surviving populations of native Darrian species that are extinct on their own homeworld.

History & Background (Dossier)

Historically Tizon has been one of the most important of the Sword Worlds, and in the past it has built an empire big enough to make it a power almost comparable to Gram (Spinward Marches 1223). Today Tizon pours its energy towards trade, science, and art. The capital city is Ny Eital; its Downport is Osgihamn Starport.

Tizona (also Tizón) is the name of one of the medieval swords carried by Rodrigo Díaz de Vivar, El Cid, according to the Cantar de Mio Cid.
