Astra is an ecumenopolis in the Tarea System, and one of the de-facto capitals of the United Nations of the Flower Galaxy. It is the most populated planet in the Flower Galaxy, and is composed of sixty four layers of cities.


Originally a lush planet, Astra is a fully civilized world, and also one of the most significant worlds to ever exist in the Flower Galaxy. It's colonization began shortly after the formation of United Nations of the Flower Galaxy.

Before colonization, the planet was a perfect terra for life, It hosted thousands of species of wonderous flora and fauna. Filled with many bustling streets, factories, and skyscrapers. Astra is the most populated ecumenopolis planet in the entirety of the Flower Galaxy.

Astra was chosen as the capital of the United Nations of the Flower Galaxy because of its location near the center of UNFG territory and the fact that it was not in the official territory of any civilization, to avoid disputes. Astra was basically colonized for this purpose.



Centralis, filled with thousands of different buildings.

Centralis is the largest province on Astra, and the most populated portion of the planet. It is filled with thousands of skyscrapers, entertainment buildings, and many other large buildings. Thousands of cultures, and spacefaring species live in this city, making it very diverse.

Centralis is also the site of many government buildings of the United Nations of the Flower Galaxy, including the Council of Nations, a vast building designed to house and feed over a thousand individuals of different species, the representatives from various nations in the UNFG, so they can discuss various laws and treaties with outside nations and generally govern the galaxy.


Vyre is the second most powerful province and is home to the vast majority of the heat sinks of the planet, due to its position over the south pole. Vyre has an outsize role in ruling Astra, as if it doesn't get what it wants, it can shut down the heat sinks and burn everyone to death.


Staralae would be wholly unacknowledged outside of its immediate planetary vicinity if it weren't for the Staralae university, the foremost educational site in the entire Flower Galaxy. All citizens hope to be educated by its personal AI virtual tutors, which, due to advances in Artificial Intelligence, vastly increases the number of students that can be taught at Staralae.


Astra has six moons, due to its relatively distant orbit around an F-type star giving it a large sphere of influence.


Zenaraca from above

Zenaraca is less densely populated than its parent planet, as a good portion of its surface is still reserved for natural spaces. Zenaraca also grows much more food than Astra, supplying much of its food. The moon grows heavily genetically modified crops, designed to grow absurdly fast under the right light, and vat-grown meat.

Minor Moons
