The Andha'Sisha are a species of outwardly human primates descended from ancient avian species and have evolved to suit the environments of their world. They have strong, hollow bones developed from their avian ancestors and also have around 2/3 the mass of a human of the same height and physique. They have orange-yellow blood compared to a human's red-blue blood, and this is due primarily to their nearly superfluously extreme immune system developed from the near extinction of the race many millennia ago due to disease. There are also a number of other biological factors in this. Due to their blood color, Andha'Sisha seem to have yellow mouths and blush. Andha'Sisha who do not live an active lifestyle will have a very hard time living, as their bodies are susceptible to muscular atrophy if they do not exercise often.
Andha'Sisha are not quite as genetically diverse as humans, as there are only three main races and two sub races. There are the Setla'Sisha of the snowy northern polar regions. These alabaster-skinned people tend to be much bulkier than other races, and also have the highest chance for a genetic mutation resulting in one of the sub races - Shadow Walkers are revered by the Andha'Sisha as heralds of fortune and blessings from God. The Setla'Sisha have also founded the main beliefs of the Andha'Sisha, a belief in an insane but loving, caring god by the name of Kefla. There are also the tanned Aria'Sisha of the desert tropics in the central continent. They are the most renowned race of the Andha'Sisha and tend to be what anyone thinks of when they hear of the Andha'Sisha. They tend to have longer bodies and deep craniums when compared to other races. The Aria'Sisha have a moderate chance of the genetic mutation breeding Shadow Walkers. They are the most numerous and most environmentally hardy race, having come from deserts and savannas. Finally, the dark-skinned Tarea'Sisha were the conquerors. Benevolent, Imperialistic, and overall pretty chill, they sieged their rival countries who would not join them, in the hopes that by coming together, they would make peace. Coming from the temporate southern pole, hey are the heads of government and the reason the Andhi'Sisha can afford to resolve not to hurt each other at all. The Tarea'Sisha produce an herb in the form of a flower, that when burned (commonly as incense, sometimes like a cigarette), will create a sensation akin to a high. The Tarea'Sisha have no chance to breed Shadow Walkers, every one of them being a Light Strider.
Shadow Walkers have a relatively uncommon genetic mutation in the eye which causes it to glow. They can see perfectly without light, due to the light emitted by their eyes, but at a cost - any amount of light above the time of dusk will burn their eyes. They have created special visors to counteract this, but before then, Shadow Walkers were either nocturnal, or as good as blind. The eyes of a Shadow Walker can have one of two colors - red or purple. The color of their eyes determines what they see. Red-eyed Shadow Walkers see the world in infrared vision, while Purple-eyes Shadow Walkers see the world in thermal vision. This is due to the color of the eyes giving off ultraviolet or infrared light alongside visible light. Light Striders, however, can have either brown or amber eyes.
Andhi'Palntes is the world of the Andhi'Sisha. It is much larger than earth, has a higher gravity, and greater Hydrogen concentration. Many species not native to the planet will not only be overweighted, but also light-headed by the planetary conditions. It has three main regions with outlying islands in between. The polar north is a cold tundra filled with evergreen forests and snowy mountains. The equatorial deserts are hot and dry, but there are many oases to support plant life and settlements. The temperate south pole is filled with leafy forests and is very warm despite being polar. Andhi'Palntes has a polar tilt and revolutionary style which causes the north pole to always be tilted away from the sun, and the south pole to always be tilted towards the sun. It is hottest at about the 47th degree of latitude.

Andha'Sisha
A species evolved from birds with virtually no outward differences from a human. They have yellow blood, low mass, and healthy lifestyles, and aren't very advanced. There are three main races and two sub races. The main races include the white-skinned Setla'Sisha, the tanned Aria'Sisha, and the dark Tarea'Sisha. The subraces are the night-eyed Shadow Walkers and the commonfolk Light Striders.

Andhi'Palntes
A large, tilted planet with high gravity and hydrogen concentration. Most of the land is arid in the central continent, although the polar regions have abundant forests. The north pole is a cold tundra while the south pole is a temperate woodland. It's not heavily civilized, but what cities are there are grand and open.
