The eleventh planet of the primary of the Nivenia System, A11, is currently moving away from being a mining colony for the Nivenian Empire, and moving towards being a diplomatic, administrative, and cultural hub. The planet's newly-exposed oceans used to contain a high concentration of ammonia, so a large portion of the fixed nitrogen in the Nivenian Empire used to be mined here. However, almost all of the ammonia has been leached from the planet. The planet was terraformed partially through a combination of waste heat warming up the planet and ammonia boiling to increase the pressure, and the terraforming was finished later by an actual directed and concerted effort using a fusion-powered artificial sun.

A11 has a high population, mainly living in huge cities, which cover several percent of the planet, and can be seen reaching several kilometers high. The economy is slowly shifting from secondary industry to a service-sector economy, making this planet one of the best places to live in the Nivenian Empire.

A11 is also interesting since it is where most of the diplomatic matters of the Nivenian Empire take place. The trade agreement made immediately after first contact with the New Cyrannian Republic happened in the Colonial province of A11, and the Republic now has an embassy on the planet.

A11 is also home to the new JEcumenopolis built by JCompany! Come now for wholesale JSector merchandise!


A11 relies both on chemical industries and service-sector production for its income, and imports more complex things such as electronics and fusion generator components from Nivenia Prime, but also exports things of medium complexity to more agricultural areas such as the ringworlds.

A11's economy has strong ties to the planet's two moons, A11.1 and A11.2.


The Colonial Province[]


  • Population - 452,893 Million
  • Jobs - 137,838 Million
  • Area - 2,000,000 km^2
  • Population Density - High, one of the most densely urbanized areas on the planet
  • Location - Near the equator
  • Terrain - Icy plains

The Colonial province, mainly a huge city, is where the planetary seat of power is. An oligarchicly elected planetary coordinator controls the workings of the planet from here with an extensive bureaucracy in a monolithic building similar to the one on Nivenia Prime (just much, much smaller, at 50 km x 50 km x 5 km high). The Colonial province also contains many chemical plants, refineries, and research institutions. The urban portions of the Colonial province typically consist of two to five kilometer skyscrapers packed closely into city blocks. Ammonia coolant connected to subsurface radiators prevent the city from overheating or melting the ice below it.

The New Cyrannian Republic Embassy[]


  • Population - 16,782,903 (12,342,014 from the New Cyrannian Republic)
  • Jobs - 19,082,483
  • Area - 200 km^2
  • Population Density - High, as this is an urbanized small area
  • Location - Embedded in the outskirts of the Colonial Province
  • Terrain - Icy plains, metal floor, plexiglass dome

The New Cyrannian Republic Embassy is the main diplomatic channel between the Nivenian Empire and the New Cyrannian Republic. In essence, it functions as a small piece of the Republic inside of Nivenian territory. The Embassy closely resembles the Republic on the inside, having a different architectural style than normal Nivenian buildings, to provide the ambassadors, staff, and guard with comfortable and familiar surroundings. Many of the wealthier Nivenians also frequently visit the Embassy to purchase Republic-made products.



  • Population - 181,095 Million (154,230 Million from JCompany)
  • Jobs - 320,778 Million
  • Area - 500,000 km^2
  • Population Density - Very High
  • Location - Near the Colonial Province
  • Terrain - Icy plains, metal floor, metal ceiling with radiators, space elevator

The JEcumenopolis is basically an oversized JTrade Center built by JCompany in late 20 NE, while also being a small chunk of Ecumenopolis on A11. It provides A11, and the rest of the Nivenian Empire, with JGoods and JStuff from the JCompany through a wholesale-retail system where Nivenian Corporations buy JSector goods wholesale and sell them retail for elevated prices. As there are so many citizens in the Nivenian Empire, JSector JGoods and JStuff have fluctuating, but high retail value. This region also acts as an outlet for the Nivenian food surplus and a place to sell industrial equipment.

Major imports from the JEcumenopolis include: JGoods, JStuff, pre-fabricated JBuildings, green spice, and more!

Major exports to the JEcumenopolis include: Food, industrial equipment, all sorts of DIY kits, nuclear-powered appliances, and more!

To illustrate this monumental achievement, Tycoon JOmnivore personally attended the inauguration on Neochios 54, 20 NE.

The Nullian Embassy[]


  • Population - 47,801,234 (38,091,245 from the Null Empire)
  • Jobs - 69,012,485
  • Area - 120 km^2
  • Population Density - Very High
  • Location - Embedded in the outskirts of the Colonial Province
  • Terrain - Icy plains, metal floor, plexiglass dome

The Nullian Embassy is the main diplomatic channel between the Nivenian Empire and the Null Empire. To maximize trading opportunity, the embassy was broken up into three sections, the embassy proper, the Mega-trading center, and parking lots. The entire embassy is under a two-kilometer high lead-lined dome in the shape of a three-dimensional isosceles trapezoid to protect from radiation.

The embassy proper is a lead-lined metal cubic building one kilometer on a side, with one hundred floors designed to emulate the conditions on Elum as closely as possible. There areas act as a sort of nature preserve, while twenty floors near the top of the building allow for luxurious apartments, diplomatic chambers, and sections customizable by Nullian diplomats.

The Mega-trading center was designed to serve the hundreds of billions of Nivenians with the interest and money necessary to buy Nullian products. As the supply is limited to what can be brought in by a few tens of millions of Nullian merchants, and there are half a billion times that in potential buyers, prices have soared to exorbitant rates. This makes it a huge economic boost to both empires' economies. It is a two hundred story, seven hundred meter-high building with a surface area of one hundred square kilometers built around the embassy proper.

To create parking space for the customers and merchants, a massive parking garage was built, covering eighteen square kilometers and containing one hundred levels, with space for sixty million motor vehicles. The remaining square kilometer of space is taken up by multi-level roads.

Small Embassies[]

Platixi Embassy[]

  • Population - 21,209 (13,548 from the Platixi Empire)
  • Jobs - 87,092
  • Area - 4 km^2
  • Population Density - Medium to High
  • Location - Light suburbia, some of the most remote regions of the planet
  • Terrain - Icy plains, metal floor, plexiglass dome


For the history of A11, and the Nivenian Empire at large, please refer to this page for a comprehensive history.


Nivenia A12 was one of the first to implement a "radical terraforming and urbanization" policy, as it was called by the planetary government, which was inspired by the resounding success of the Thadus 0037 colony's terraforming project, and the ongoing (at the time) terraforming of Nivenia A12. It should be noted that Nivenia B4 was being terraformed at this time as well.

A timeline the terraforming project is shown as follows:

  • Terraform from low T1 to high T1 - Novemex 35, 36 NE to Ianuaria 34, 37 NE
  • Terraform to T2 - Ianuaria 35, 37 NE to Novemex 34, 37 NE
  • Terraform to T3 - Novemex 35, 37 NE to Ianuaria 34, 38 NE
