     Lujenar's Beginning  

Lujenar is slightly older  than the planet Earth, making it approximately 4 billion years old. Life began to form about 3 billion years ago.  Today Lujenar is a plush tropical planet, much like Earth's Hawaii, but in the beginning it was a dry planet with little to no water. The atmosphere was very toxic, consisting of carbon dioxide, hydrogen, nitrogen and ammonia.  All these toxic vapors mingled with those of the volcanic ash and heat that spouted out as it erupted, causing the land to become encased in a gray toxic covering. The solar energy from the Gutrabar star was,however,able to filter through the gray clouds, providing warmth and energy. The constant eruptions heated the water and shifted the land masses around. By taking a quick look at Lujenar's early beginnings one would presume that no life could ever be sustained.  However, that is not the case, life on Lujenar began in the depths of the little water that surrounded the land. The water contained nutrients, carbon compounds and other traces of elements found in the universe, and it was here that life on Lujenar began.

Lujenar's First Signs of Life    

Far away from the toxic fumes that once covered the sky, in the depths of the water, tiny microscopic organisms began to pull nutrients from the water to harness energy. Little by little they began to slowly form and reproduce themselves. The first known single celled prokaryote was known as "Lujens."  "Lujens"  began to slowly evolve by gathering the basic necessities needed to gather genetic material. The "Lujens" structure was formed by  cytoplasm, mitochondria, a tiny chloroplast, and RNA which aided in fission of the cell, allowing for sexual reproduction. As the "Lujens" began to take over the water world they used the toxic carbon dioxide as a means of respiration. This in turn allowed the  chloroplast found in their structures to produce oxygen.  The "Lujens" pushed the oxygen out as waste and began to build great amounts on the top surface of the oceans. The oxygen then  slowly began to filter out through the vents in the land caused by the volcanic action.     

As the oxygen accumulated and pushed its way out into the open air the atmosphere began to change.  After all the volcanic activity was done the water had become warm enough to incubate and house the cells that would later produce Lujenar's future life forms.  Oxygen was able to float into the air allowing organisms to breathe both in and out of the water.

    The Evolving Lujen   

The Lujen began as a simple organism that was unable to move around.  Instead it lived its life floating in the currents of the ocean and settling in the rich mud. As time progressed, so did the evolving Lujen. The early Lujen evolved into the Alpha Lujen, which, in turn, allowed other forms to reproduce and thrive.  The Alpha Lujen developed and organized a cell nucleus that contained DNA.  These organisms were the first eukaryotes (cells with nuclei) to inhabit Lujenar. With the help of DNA, sexual reproduction became the primary way for organisms to replicate. Later, multicellular life forms evolved which not only reproduced differently than the early Lujens, but were also able to move around in both sea and land, allowing for a variety of organisms to inhabit the planet.


The following are some examples of evolved Lujens:
Omega Lujen: These organisms move about by oozing out their form, since they do not possess a fixed form.  They ate by surrounding and enveloping their food with their body.  They are like the amoeba that is found on Earth.
Hydra Lujen: These small creatures evolved into multicellular life forms that move around with their cilia. They have a false body cavity that emits a luminous silvery light.  This luminous effect is attributed to the nutrients that they consume from the volcanic soil found in the depths of the water. These creatures continue to flourish in the ocean.  They are also a source of food for all other aquatic life. They resemble the plankton that lives on Earth.
Cillatic Lujen: These cells began to grow hair-like follicles that allowed them to move around in their environment. Due to their mobility they were able to spread out through the water and eventually evolved into land creatures.

Lujenar's Life Continues

All cells on Lujenar have thrived in different environments. The warm waters of the ocean allowed cells to evolve into large life forms. With the humidity and rich nutrients found in the water the cells were able to keep their chloroplast functions. With the help of oxygen build up, other forms were able to flourish and evolve. The earliest life forms that began life on Lujenar resembled those of fungus, algae, legless lizards and aquatic plants that eventually evolved into land plants.
