Three politically dominant species make up the Citadel Council at the inception of the series: the asari, a feminine mono-gendered species who favor centrism, republicanism, diplomacy, biotic abilities and guerrilla warfare tactics over raw military power; the salarians, an amphibious species who have an aptitude for liberalism, technocracy, technological research, espionage and unconventional warfare; and the turians, a proud avian-like species known for their conservatism, stratocracy, disciplined honour culture and military-industrial capability. Membership of the Citadel Council is eventually expanded to include a human representative by the end of the first game. Other associate races on the Citadel include the volus, a client race of the turians who mostly make their influence felt through trade and commerce to compensate for their small and fragile suit-covered bodies; the hanar, an overly polite and philosophically inclined species of jellyfish-like entities who worship the Protheans as their progenitors with religious fervor; the reptilian drell, who loyally serve the hanar as part of a symbiotic relationship which they call the Compact; and the elcor, a species of hulking elephantine quadrupeds who preface everything they say with the intended emotion due to their lack of vocal inflection and discernible facial expressions.
