The LEGO Castle Dragon Mountain (70403-1) set portrays a pivotal medieval confrontation. Within its 381 pieces, two King's Knights challenge the formidable Dragon Wizard and his Dragon soldier to rescue the captive princess. The mountain stronghold features a towering structure complete with a dungeon, a spiral staircase, and a dragon nest concealing the King's stolen gold in a secret compartment. A functional large catapult, equipped with wheels, aims to breach the tower's defenses, allowing the knights to access the hidden potion room and free the princess from her dark cell. This build focuses on strategic siege play and the quest for hidden treasures.
