Sapiens are a species of human more formally known as Homo sapiens. The name Sapiens is used to differentiate the Earth-native species from other humans transplanted during Earth‘s prehistory. Sapiens are the dominant species in the Compact. Sapiens, like all humans, are considered primates, sapient bipedal mammalians. On Gohem, the Orag species, descended from Neanderthals, refer to Sapiens as “terrags” and Earth as “Idin.”

Prior to formal first contact, the Gelt frequently referred to the occasional Sapiens they encountered as “Tianese,” Tian being both the most frequent homeworld or nearest large core world of origin and the financial and cultural center of the Compact.
