The League of One was one of the salarian intelligence services at the time the salarians discovered the Citadel. Their primary training was in espionage and assassination. Never more than a dozen strong, the team was adept at infiltrating the tightest defenses and eliminating all necessary obstacles. No further incidents were reported and it was assumed the League was wiped out. Some recently declassified documents, however, have suggested there may have been a thirteenth member who eluded the salarian military.
