100th Millennium Wiki

Edana is the homeworld of the Edans and the temporary homeworld of the Perathri and Myreani. It is surrounded by a huge cloud of orbital habitats which house more than two thirds of the planet's population.


Edana is the third planet in the Ardaya System, and is the most populous planet in the system. Formerly a harsh, desert world, the planet was terraformed to be suitable for many species during the process of transforming the Ardaya System into a vehicle to escape the Myrmidan Galaxy. Anything going to Edana or its two moons is exceedingly well searched, as Somnar Hive spies attempt to sneak in and sabotage the elaborate escape plan.


Edana is a relatively flat world with only one high mountain, the extinct volcano of Mount Hope. The planet has a static-lid crust, and no plate tectonics, so any mountains are hostpot volcanoes. The planet has very large oceans, which are filled with life and even some intelligent species emigrated from other planets. The endless plains are covered in prairies and savannas, with the occasional arcology every few miles.

The most geologically interesting portion of the planet is Mount Hope, the tallest mountain on Edana. Mount Hope is a recently extinct volcano almost twenty kilometers in height and has vast and dangerous cloud forests. The cloud forests of Mount Hope are filled with exceedingly dangerous plants, many of which are carnivorous, and will be explaned later. Mount Hope is hypothesized to have a huge magma chamber which is slowly pressurizing and pushing up the mountain to greater heights. However, soon this magma chamber will drain out and the vast mountain will stop rising.


The savannas of Edana are covered in tall grass which occasionally flowers, not much interesting about that. The really interesting portion of the planet in terms of flora is the cloud forests of Mount Hope, which are filled with huge, dangerous carnivorous plants. Examples of this include a huge plant species of varying size, capable of devouring and digesting species, depending on its size, from human size to Carlean size. Needless to say, its a good idea to avoid these.

There are also huge pits hidden in the ground, which it is not a good idea to fall into because there's a pool filled with digestive juices at the bottom, with a form of bait specially designed to lure in unlucky wildlife from the savannah below. These are usually found further down the mountain, beneath the clouds.

Needless to say, the cloud forests of Mount Hope, albeit interesting, are very unsafe to travel around.



Edana formed with the rest of the Ardaya System, approximately 2.7 billion years ago. It probably formed without moons, but the impact of a Kelar-sized object vaporized the entire object, causing it to temporarily transform into a synestia. The majority of this cloud of debris collapsed back into Edana, but its two moons Ulekka and Seltina were formed from this cloud.

After this occurred, Edana and all other planets in the solar system were bombarded with rocks in the Late Heavy Bombardment, causing Edana to be sterile until approximately 2.3 billion years ago, when the first life formed. Life stayed microbial for the next two billion years, until multicellular life suddenly appeared in huge numbers. Over the next 400 million years, life evolved rapidly into hugely diverse species, ranging from tiny worms to vast herbivorous mammals. Most importantly, the reptilian genus Edan began to evolve.

Evolution of the Edan

The genus Edan consisted of approximately five sapient and subsapient species at its height, but as the most powerful of them either wiped out or interbred with the other four, it was winnowed down to a single species, simply called the Edans. This species spread out across the planet, founding various civilizations.

These civilizations eventually united into the United Edanan Civilization, and space travel was attempted, with colonies being established on Ulekka and Seltina a few decades afterwards. Kelar and Xathor were also colonized by intrepid groups of people, and a research base was established in orbit of Thulinar. Eventually, just as the Edan was beginning to send probes beyond its solar system, the Somnar Hive reached the region of space surrounding the Ardaya System.

The Ardaya Conflicts and Modern times

As species living near the system flooded into it to escape, most other species would have kicked them out. However, the altruistic Edan welcomed them and began signaling for help from the more powerful extragalactic nations. The UNFG, still reeling from the War of Saiheran Succession, was reluctant to help, but the EFS and FTIC both sent aid in the form of advanced technology and materials. All the free inhabitants of the galaxy piled into the system and fortified it against attacks from the Somnar Hive, which occurred almost daily.

They unified into a nation known as the Last Free Systems, and began hastily constructing a Caplan Thruster. Luckily the plans for a functional one were already there, as the Free Nation of Garrea's Meral Project was ongoing at the time. It is being constructed in record time, and as of the present day is almost complete. It will propel the entire system clear of the Myrmidan Galaxy towards the Exurian Cluster, where it will settle into a new location free of the Somnar Hive.


Only one stable hyperlane leads into the Ardaya System, that which the entire system is being prepared to follow for its departure from the galaxy, and remains of older ones are found scattered through the system's Oort Cloud.

Given its high and diverse population, Edana is extremely difficult to govern. Many criminal organizations reside in the poorer areas of the planet. Anywhere from deeply-bored tunnels reaching well into the mantle to the vast number of space stations orbiting the planet, one can find dangerous criminals, rogue machines, and all manner of unsavory individuals the government would rather do without.

However, most of the planet is perfectly fine for normal civilians to live in, despite its fragmentary political state. A large fraction of the planet's savannahs are covered by great tower cities, vaulting almost to the edge of the atmosphere. These tower cities hold most of the planet's surface population.
