Castle: Dragon Masters

Dragon Masters (1993–1995)
The Dragon Masters collection was released in August 1993. Majisto the Wizard (known as Merlin the Wizard outside of the U.S.) and his glow in the dark wand were introduced to the Castle series. This was the first time for Lego Castle to have a fantasy theme. The powerful wizard commanded his own organization of knights, the Dragon Masters. Their goal appeared to be the capture and possible taming (for use in battle) of fearsome fire breathing green dragons with red wings. The dragons were another new element to the series. The Dragon Master knights had newly designed faces, and were characterized by shields identical to the ovoid shields of the Black Knights except they featured a green dragon instead of the blue dragon. The Dragon Masters consisted of magic and mythical themes. The largest Dragon Masters set was Fire Breathing Fortress. Other main sets were Majisto's Magical Workshop and Dark Dragon's Den. The total number of Dragons included in the Dragon Masters sets was only three.

In Europe and Asia, a total of seven Dragon Masters sets were released in 1993. But in North America, only four sets were released that same year. The remaining three sets, Magic Shop,Dragon Defender, and Medieval Knights were released in 1994. One possible reason why this occurred was because in 1994, no new castle sets were planned to be released. Therefore, it was decided that these sets would fill in the gap. Other smaller Dragon Masters sets were released in 1994, such as Majisto's Tower and Dragon Master Chariot but they were only mini castle sets. The last Dragon Masters set was Wizard's Cart that featured Majisto carrying his favorite wand and traveling with a cart (loaded with a treasure chest), in 1995. This marked the end of the Dragon Masters reign. But the Dragon Masters sets inspired other castle sets to have magic and fantasy themes such as the Fright Knights.

Royal Knights (1995–1996)
The Royal Knights were the first Lego theme to have skeletons, starting with the first ever skeleton set "Skeleton Surprise". Their leader was the Royal King. Their largest set was the 6090 Royal Knight's Castle. This faction also introduced the fan favorite silver longsword, which is used by the Royal King.
