Homeworld of the Danuil and Roknoir.


A temperate E-Class world, Isadanh (RS 8409-2303-7-309848-218 in 9.7.1.) is 17631.1 km in diameter and has a gravity of 1.1 G. With a semimajor axis of 0.6 AU the planet’s year is half that of Earth at 184.9 days. Their local day is remarkably Earthlike at 22 hours and 59 minutes.

The entire system formed over 10.9 billion years ago. Isadanh has eight moons, two of which are temperate D-Class worlds named Rucaon and Utlarr.


The atmospheric pressure of the planet is 0.8 and it has a local mean temperature of 8.5 °C. With an axial tilt of only 17°49’ the seasons of Isadanh are more mild than those on Earth but still relatively cooler.

Being mostly land, Isadanh should have been a desert but this was averted due to large underground aquifers plus the fact that there are more hurricanes on this world than there are on Earth.

Because of the lack of surface water and the ferocity of the storms, plant life on Isadanh, especially large trees, have evolved to grow stronger and deeper roots. This caused massive forests to grow almost all over the planet. These trees have also evolved to be bioluminescent, casting a very calming and very fantasy-like glow on the ground. The bioluminescence most likely evolved because the smaller trees weren’t getting enough light due to the massive branches of the larger trees blocking out sunlight.

The trees of Isadanh can also be hollowed out if needed and used for shelter, which is what the early Danuil did to escape from the storms of their planet.

The oceans of Isadanh are little more than large seas when compared to terrestrial oceans. They are full of life. Like the trees the oceans have their own bioluminescent life form that lives close to the surface, this life form being a seaweed analogue.

The planet, along with its system, formed from interstellar dust around 10.9 billion years ago. Like most planetary formations the larger interstellar rocks collided and formed the planets of this multistar system. Unlike Earth’s own moon, the two D-Class worlds seem to have been made separate from Isadanh and entered its orbit during its late bombardment stages. The other six asteroids came in later.

The evolution of life on Isadanh has been remarkably slow for a world with a short year like Isadanh, but this could also have something to do with the more mild seasons, if one could call them seasons. Slowly but surely plants and animals evolved into a more cooperative and beneficial relationship than to the animals on Earth. This is one of the very few planets where a sapient species has evolved so similarly to that of another world’s sapient species, in this case, the humans of Earth. It supports, if loosely, the Theory of Parallel Evolution.

The first recorded evidence of early Danuil is dated at around 500,000 years ago near one of the larger freshwater lakes. They evolved from an earlier form of a blonde furred creature that was remarkably like a simian, but a xeno-simian with much more, for lack of a better word, class.

The early Danuil spread out around their small lake, not willing to head into the dark forests. As the generations passed, their blue fur disappeared until only they had long flowing hair.

With the generations their intelligence had grown and they’d begun to take deeper journeys into the forests for food and wood as well as other supplies they might need.

Still in the hunter-gatherer stages, groups of Danuil headed deeper into the forests, forming traveling clans that began to spread across the planet. Some stayed behind and began making primitive settlements in the trees and ground near the lake.

As the Danuil spread across the planet a small genetic mutation began to occur within them. The Danuil who went north developed lighter skin and much longer and pointier ears while keeping their long blonde hair. The ones who went south developed shorter ears, darker skin and auburn hair that was slightly curly.

The two similar but distinct races began growing in numbers, slowly beginning to build small towns and cities within the massive branches of the trees of the planet. Over 15,000 years ago both races rediscovered each other. The differences within them both led to their being a large war. Their technological level at the time was around that of the Middle Ages.

This war led to the Southern Danuil being enslaved for over a thousand years by the Northern ones. Both races know this time in their history by different names. The Southern Danuil know it as the Dark Times while the Northern Danuil know it as their Golden Age. After a thousand years of slavery the Southern Danuil rebelled and destroyed much of the great civilization they’d been forced to build.

After the rebellion, both side gathered to attempt a peace to stop the bloodshed. The Northern Danuil apologized for their arrogance and gave the Southern Danuil their lands and properties back.

At this time, a great plague suddenly struck the Danuil. Those infected became ravenous for meat of any kind. The Danuil, eating mostly vegetables, feared this plague and united in their cause to help either contain or find a cure. Within a few years a vaccine was found. The immunity factor could be passed on genetically. However, no cure was ever found and the infected had to be killed. It is rumored that some escaped into the equatorial mountains and moved themselves into caves. The

infected became known as the Roknoir, or Deformed Ones.

Over the next few thousand years

Danuil technology stood at a standstill. When discovered by the humans in 8015 they had spread far across their planet and had many large medieval-type kingdoms. Surprised by their remarkable resemblance to elves of human myth and story a large research station named Lothlórien was built in orbit of the planet. However in the year 8030 disaster struck. An asteroid struck the station and it fell into the atmosphere of the planet. However, miraculously, the station fell in such a way that there were very little casualties and everything seemed to be relatively intact. It landed on the east side of a small mountain overlooking one of the smaller lakes. Because of the Lothlórien Incident, unintentional first contact was made between the Danuil and humans as well as the reestablishing of contact between the Roknoir and the Danuil. The Roknoir had evolved to become shorter in their mountain cities. They had become tamer but were more violent than their Danuil brothers. They even had grown facial hair. They had begun to resemble dwarves in appearance and manner as they were masters of crafts and mining.

Since first contact between the three races the Danuil, and to a certain extent the Roknoir, have attempted to reach the stars to match their new round eared brothers. Humans have offered small assistance where they feel it’s safer to do so but for the most part allow the two races to make mistakes and learn from them.

The crash site of the Lothlórien space station became a large city inhabited by humans, Danuil and a few Roknoir. The city is also named Lothlórien.


Danuil culture, both Northern and Southern, is one based off of a more harmonious approach to their environment. Because the trees protect them from the majority of the massive storms on the planet they have never seemed to be at odds with their environment due to the fact that there are very few predator animals on the planet.

It wasn’t always this way. In the past wars were fought constantly over food and resources. It wasn’t until the Southern Danuil rebelled that they began to attempt more peaceful approach to their lives. Both Northern and Southern cultures coexist as peacefully as they could. However this had greatly stagnated their technological development until the Lothlórien Incident.

The Roknoir culture, while younger than that of the Danuil, is still rich in history and tradition. As the Roknoir are former mutated Danuil, they possess a few commonalities with the Danuil physically. Thanks to the virus messing with the personalities of the infected they became more carnivorous. They also enjoy mining for precious mines and jewels. They also enjoy making weapons, jewelry and armor for their battles with the beasts that live in the inner caverns of the equatorial mountains.
