A term referring to any individual born of two distinct sapient species. Though technically referring to individuals who are sired in equal parts by two different sapien species, the term is commonly applied to any being of mixed blood. At one time, these individuals were quite rare. As the integration of intergalactic communities continues, they are growing increasingly common due to the proliferation of cross-species relationships. Individuals with a greater than fifty-percent proportion of mixed species heritage are significantly less common, as half-breeds are typically born sterile. Despite continued proliferation, the existence of half-breeds is a taboo subject in much of society.
