The Sikari are a humanoid alien race which evolved into five distinct branches on the planet Sakar. The Sikari were characterized by their leathery skin, reptilian eyes, and fierce temperments. The skin of a Sikari was made up up thousands of overlapping scales, which could be shifted to cover wounds to protect them from infection. All five races are genetically capable of interbreeding; 93% of the offspring from such unions resemble only one of the parents. There were a number of environmental and geological changes that greatly affected life on Sikar, causing the once-singular Sikari race to evolve its five unique races. Chief among these changes was the radiation expelled by the nearby star M'dweshuu. The Red Sikari, called Kajain'sa'Sakari, evolved in the deserts. They have ridged foreheads, eight small horns around the eyes, and two at the chin. They breath through a permeable membrane over their mouths and through four breather tubes on their necks. The Green Sikari, known as Kadas'sa'Sikari, evolved in the forests. They are visibly scaled, with obvious noses and small horns ringing their eyes. The Mountain Sikari are called Esral'sa'Sikari, and have smooth skin. Their ears are large and fin-shaped, designed to be extended or pulled flat to regulate body heat and enhance hearing. They also have a nasal membrane similar to the Red Sikari. The Pale Sikari, called Gluss'sa'Sikari, are found in the islands of the planet. They resemble the Green Sikari, with fin-like ears. The last race, called M'shento'su'Sikari or Southern Sikari, lack any horns but have a number of breather tubes at various points on their skulls. Their inner strength and fierce nature has been honed over millennia of survival against the predators of Sikar.
