The Eridani Light Horse is a fictitious mercenary group in the science fiction universe of Battletech. They're featured in the games Mechwarrior 3 and Mechawarrior 3: Pirate's Moon. "We, the Eridani Light Horse, chose not to travel with General Kerensky on his Exodus. Instead, we stood in silent attention as he and his armada of ships departed, for we knew in that moment one era of history had ended and another had begun. We honor him and his beliefs to this day with the black ring around our insignia and by flying our banner always at half-mast. We will always speak the name of the General with respect for we have stood for these hundreds of years since his departure in defense of the Inner Sphere, awaiting a return to the glory of the Star League.
