Caelum Prime (Kay-el-um Prīm)

As seen in


  • Grassland (area: 174K mi2)
  • Taiga (area: 125K mi2)
  • Wetland (area: 90K mi2)
  • Temerate Deciduous Forest (area: 108K mi2)
  • Tropical Seasonal Forest (area: 67K mi2)
  • Temerate Rainforest (area: 55K mi2)
  • Savanna (area: 54K mi2)
  • Cold Desert (area: 47K mi2)
  • Tropical Rainforest (area: 30K mi2)
  • Hot Desert (area: 28K mi2)
  • Tundra (area: 22K mi2)
  • Mountains (rough area of 105K mi2)
  • Total Land Area: 905K mi2
These land areas only take up about 20 percent of the surface area. The other 80 percent of the surface area is covered with water, whether it's salt water oceans, or freshwater rivers and lakes.


Each geographic feature (biome) has its own distinct ecosystem. Each ecosystem is similiar, if not exactly like, to Earth's ecosystem. This includes flora, fauna, and everything that makes up the ecosystem to keep it in balance.   Humans, for the most part, have kept a good balance with the ecosystem they live in. The only times that this balance was truly disrupted by them was during the Industrial Era, the Space Era and the Era of War and Reversions. But balance began to be restored near the end of this last era. By the Apocalypse Shadows Era balance was restored because Humans had reverted to an almost pre-industrial time. And what remained of the Industiral side of things has been engineered to be good for the planet.

Ecosystem Cycles

Same as Earth.


Depends on which location one lives at. Cold Desert is going to have colder temperature and more snow than a tropical rainforest. The high up one is in the mountains will effect the climate one has to deal with.   Overall, climate is the same as Earth. Though by the Apocalypse Shadows Era global warming has reversed itself to the point that it looks like the ozone has almost completely healed itself. For the most part, each area has a stable climate year. Any deviances from this will be marked in the appropriate area.

Fauna & Flora

Same as Earth's just with different names. View the Flora and Fauna articles for more information.

Natural Resources

Same as Earth's.   Things like wood from the forests, stone, gems and other natural resources from mountains and the crust, grain from agriculture, and meat from wild and domesticated fauna.


Caelum Prime: A Beacon of Harmony Fractured
Earth's Descent
by Lady Wynter
Just as on countless worlds before, humanity on Earth strayed from the path of righteousness. The once-vibrant planet choked under the weight of war, famine, and despair. Gloombringers, demonic entities unleashed by the embodiment of discord, the Disharmonia, reveled in the chaos, twisting hearts and minds towards destruction.
A Spark of Hope Preserved
Infinite Grace, the benevolent creator god, surveyed the devastation with a heavy heart. Yet, amidst the darkness, a flicker of hope remained. A small group of 333 humans, diverse in their beliefs, held fast to principles that resonated with Infinite Grace's own: Compassionate Living, Spiritual Exploration, Service to Others, and Acceptance of Diversity. Notably, 33 of these humans carried a fading echo of the once-thriving Egyptian religion, a testament to humanity's capacity for spiritual exploration, even in the face of oblivion.
Exodus to Caelum Prime
Recognizing the potential for these chosen few, Infinite Grace orchestrated a daring rescue. He transported them to Caelum Prime, a pristine world teeming with life, a haven untouched by the Disharmonia's influence. Here, they could rebuild a society based on their core tenets.
A Tapestry of Nations
Driven by their core values, the 333 humans embarked on a journey of exploration across Caelum Prime. Each group, shaped by their unique experiences and belief systems, established distinct settlements. Over generations, these settlements blossomed into 31 sovereign nations, each a vibrant thread woven into the tapestry of Caelum Prime.
The Eternals: Guardians of Harmony
by Lady Wynter
Knowing the Disharmonia's relentless nature, Infinite Grace manifested the Eternals – celestial warriors imbued with immense power to defend against the Gloombringers. These formidable protectors stood vigilant, safeguarding Caelum Prime for millennia.
A Breach in the Defenses
The Eternals held strong, repelling the Gloombringers' overt assaults. However, the Disharmonia, ever cunning, began to subtly influence Caelish society. Whispers of discord, prejudice, and greed arose, chipping away at the foundation of unity established by the core tenets. The Gloombringers, seizing this opportunity, found a new way to infiltrate Caelum Prime. This time, they came not as rampaging demons, but as insidious whispers, manipulating vulnerabilities and exploiting societal divisions.
The Shadow of the Egyptian Legacy
The once vibrant Egyptian faith, brought by the 33 humans, had faded over generations on Caelum Prime. Though remnants of their reverence for the interconnectedness of all things lingered in some cultures, it no longer held the power to be a strong counterpoint to the Disharmonia's influence.
A New Threat Emerges
The Gloombringers, ever-evolving, have unleashed a terrifying new weapon: monstrous mongrels, twisted hybrids of the native Caelish fauna and the essence of the Disharmonia. These creatures are ferocious and relentless, driven by a hunger to consume. Additionally, the insidious whispers have given rise to a horrifying phenomenon – the Eaters. These are once-living Caelish people who have succumbed to the Disharmonia's influence, their bodies and minds corrupted into mindless, flesh-consuming creatures.
A Call to Unity
With the threat more dire than ever, the Caelish people must rediscover the core tenets that brought them to Caelum Prime. They must confront their differences and find strength in their diversity. Perhaps, by rediscovering the forgotten wisdom of the Egyptians – the interconnectedness of all things – they might find the key to defeating the Disharmonia's influence and overcoming this terrifying new threat.

In the World Meta for Caelum Prime, if I recall correctly, you mentioned that you are writing a novel based on Caelum Prime. Are you actively writing? When might it be published?

Jan 3, 2024 06:12 by Lady Wynter

I have a draft. I'm expanding on what little worldbuilding I have so I can improve what I wrote. I don't have a currently date for publishing but I'm hoping summer. Earlier if I can manage. It will depend on how long it takes me to complete everything.
