100th Millennium Wiki

Sion is a ecumenopolis world and the Capital of The Republic of Sion, giving its name to this nation. It is located in the Herschel Space, in the Lewis Galaxy and the Eire System. It is orbiting the Sun Eire A, on a binary system.

Sion is a high tech world, classified as a full ecumenopolis world, reached somewhere in the last 14 millennia due to its high degree of urbanization and industrialization. It was predicted that it will become a complete ecumenopolis by 95 000 CE (74 834 ADL), but Sion became an ecumenopolis way sooner than predicted, in the 86 030 CE (65 864 ADL). This world has become a beacon of technology among the Lewis Nations, although it has been hardly criticized for its ethics. It holds the Bank of Sion and the TERGA Industries, an Android and robotic manufacturing company.

On its early stages, the planet was a colony of the United Alliance, and was settled mainly by less favoured people and dissidents. Due to some hard conditions, the planet was terraformed to suit human habitation. Firstly, farming and mining were the main economic activities, but later on, the pioneers started to build up on technology and industrial centers and turned into manufacturing. The planet became an early hard industrial world, but do to its distant location, exports where more expensive and complicated back in the day, to the more populated core worlds of the United Alliance or the other human Nations, so they turned their production towards the local demand, creating many industrial, mining and farming robots and equipment for the adjacent mining and farming colonies.

Soon, differences in economic, culture, and viewpoint turned the planets on the Germinis area towards the United Alliance. Soon, a terrorist group called the L.A.G.G.A (Liberation Attack Group for Germinis Autodetermination), colloquially known as Nandis, started several attacks on U.A worlds. This attacks and groups kept going for about two thousand years, until finally, an agreement was reached between the Nandis and the central authority and since the region was unruled and unmanageable from the core of U.A, they decided to finally grant independence to the area.

Sion, became the new capital, due to its economic importance and being the place where the independence agreement was signed. The region took the name of "Republic of Sion", since it was in Sion, where the government body and constitution was created. Thus all R.S citizens call themselves Sionese.


Most of the surface area of Sion is a massive crust of buildings and shallow parks. Sion is an ecumenopolis divided into districts and each of them is highly specialized. The previous world of Sion was a marshy planet that stood as a center of the L.A.G.G.A operational secret center. After it was chosen to be the capital of the New Republic, due to it's importance, a massive production an emigration into this world happenned and with millennia of ectogenesis, the world became fully populated and industrialized. Most of the fauna and flora were kept in massive zoo-parks or adapted to the steel world infraestructure. Most of the water marshers and ocean have been converted to provide drinking water and refrigeration to Sion.

Former Continents and Oceans

Before it's ecumenopolization, the planet was covered by 3 continents: Gehenna, Catay and Athos. There were as well about 3 oceans: Gusis, Nafias and Loxom. All three oceans are now but gone under the large massive infraestructure of the ecumenopolis. Most of Loxom however is still visible while Gusis and Nafias have become subterranean oceans. All are of course connected to each other. The small space of Loxom is used as a Marine resever for native life of Sion.


  • Gehenna: District 0, District 1, District 4, District 18

The largest continent, it expanded all the way from the north pole to all the way to the southern pole. Its climate was varied, from polar and tundric weather in the far south and north, to deep jungles in it's middle, towards the equator and mild plains, forest and large marshes and rives in it's middle south and middle north sections. It was the last to be fully covered in 85 000 CE.

  • Catay: District 2, District 3, District 6, District 19

In another time this continent was filled with mashes and lakes, nice foggy plains and even a small area of arid lands of tundra in the north. This continent also hold several mountain ranges which are now used for mining purposes. Most of it was covered by city expansion over the 84 000 CE.

  • Athos: District 8, District 9, District 16, District 17

Sion, prior to becoming an Ecumenopolis.

The smalles of the three continents of Sion, it was a set of penninsulas and islands with forests and marshes. The northen coast was filled with jungles while the south was cold. It was the first of the continents to be fully covered in a big city, in the 83 000 CE.


  • Gusis: District 10, District 11, District 15, District 21

The second ocean to be fully covered, it ended up putting togetter Athos and Catay. Full connection was attained in 85 000 CE, then the entire ocean was consumed by the massive city.

  • Nafias: District 5, District 7, District 14, District 20

The first ocean to be fully covered, it connected Gehenna to Catay. Most of it's northern section was covered, blurring the distance between Catay and Gehenna. It didnt take long for Nafias to be consumed by the city above in 84 000 CE.

  • Loxom: District 0, district 12, District 13, District 22

The last ocean to be covered by the massive city. It was the largest ocean out of the three and connected Gehenna and Athos for the most part but also Catay with the other two continents. It ended up being used as a last reserved of marine life by the end of 86 000 CE, marking the full ecumenopolization of the Planet which officially became one.

Paisaje ecumenopolis1.jpg


The history of Sion began with the colonization of the Nebula. It was a hard enterprise, as it was badly connected with the United Alliance. However, the precious metals and gases of the region attacted many colonist who endured long harships and austerity. During this time though the worlds acted as bases for industrial and mining operations and the colonization of this worlds was done slowly but steadly. For much of the time, they remained unconnected to the rest of the United Alliance and thus, faced a disruption with the rest of the nation.

After centuries, this led to the evolution of the language which later was known as Sionese.
