 Much like the Lion Knights, the Black Knights were based on earlier, non-subtheme-affiliated sets, some of which were retrospectively included in the faction.Officially launched in 1992, the Black Knights are characterized by a red, yellow, and blue wyvern dragon symbol which is only shown on their shield or flag; unlike the other factions the Black Knights never wore the emblem on their chests.The first well-known Black Knights-style set released was 6085 Black Monarch's Castle in 1988, which was also the largest Black Knights set ever released.
