Allow me to share with you a little bit of detail about the creatures I draw.

Listen close, it might get a little confusing.

These are 3 Races of a society of creatures that live far faaar underground in a large city.
Their lifestyle is based on a Caste system. What your born as determines your lifestyle and job setting.
They all work together, using their traits and skill-sets. to keep the city functioning and to ensure their continued survival.
While they are all the same Species, Each race has its own physical traits and characteristics unique to its race, These can vary from each individual while still staying within certain guidelines.
While its not unheard of. Their society practices "Endogamy," marring or having physical relations with another race is looked down upon. As such it is viewed socially taboo as it can taint the infrastructure of the society and creates abnormalities in the job structure of the city.

You have the Nakori, Nakoru, and the "Nakoro", but they are all "Nakoren"

Nakori:
Are the smallest of the 3 races. Not very intimidating stature wise but their highly adaptive nature and sharp wit allows them to overcome most difficult situations with ease.
They are good with their hands and can learn very quickly. They pride themselves in tinkering and engineering things or doing research of various kinds. Along with the important role of agriculture.
Their physical traits are small stature, usually ranging anywhere from 2'' Feet tall (being very short) to 3.5'' (being very tall) Thier eyes, noses, and ears, are usually roundish.
Their skin tone and pigment is usually paler lighter colors, while their eyes can be various colors with white scleras.

The only exception to all of this is Fulcrum. He stands at a extremely tall 4.5'' and has a dark skin tone with red eyes as well as having naturally large physical nature in size and strength.
Being confirmed of purely Nakori decent, his physical state has been viewed as a mutation.


Nakoru:
Are the middle sized race standing usually at an average of 4'' feet tall. Extremely agile and dexterous. Their skill-sets are very wide. Able to carry out various jobs as needed. Along with a hefty skill base their cunning
gets them through most situations with grace and finesse. Able to run at great speeds and jump great heights with long lasting stamina, make excellent Hunters and cartographers but of course they can fill many other roles as well. Their eyes possess a unique organ that emits a bio luminescent light in the dark that only they can see giving them a sort of night vision.
Their physical traits are very lean and slender. Larger leg muscles promote for stronger mobility. Their skin varies greatly, being many different colors and tones. They possess tails to assist in balance, how long the tail depends on the individual. Their ears are typically streamline and pointy and their noses small and sleek. Their eyes are narrow with colored scleras with slit pupils.


Nakoro:
By far the largest of the races, standing anywhere from 5'' to 7'' feet tall. While not the most intellectual race, what they lack in innovation they make up with brute force. These juggernauts are extremely strong with high endurance and stamina. Able to work long hours of hard physical labor with minimal difficulty. Their bodies are tough and durable, skin immune to most forms of abuse like cuts and bruises while being very heat resistant. Their bodies adorn natural armor plating. Their shape and size varies from each individual.

Their eyes rather boxy with varied colors while their noses being flat and close to their face. Their ears vary either ending up or down or both in a pointy or rounded fashion.


And there you have it. A little peek into Nakoren Physiology.
Untill next time everyone.
