The Calentar are a humanoid species native to the planet Calentar III. They were a people who believed that they were a higher form of species and that their planet was at the center of the universe. Their planet had a unified government led by a chancellor. The Calentar don't have individual digits on their hands and feet, like most humanoid species; instead, their digits are webbed together similar to a mitten. Their heart (or "cardio organ") is located in the lower chest (at about the location of a Human's intestines), and their pulse can be checked on the wrist similar to Humans. Their digestive tract is in the upper chest, (about where a Human's heart/lungs would be). The Calentar have a total of 31 ribs (or "costal struts"), 16 on one side, 15 on the other. Their enlarged foreheads are called "cranial lobes". In 2565, they were forced to leave their homeworld after an orbital bombardment by the Fen Domar. The 230 million refugees were transported to Earth and human colonies.
