to develop an early history of the fictional kingdom of Hyrule and create an origin story for the Master Sword. Zelda producer Eiji Aonuma commented that the game's premise was based on a desire to focus the story on the gameplay experience, which was built around the game's motion controls. He said: "This time, the theme is the sword which makes use of the Wii MotionPlus accessory... When you think of a sword in The Legend of Zelda, you think of the Master Sword. Rather early on, we decided to address the origin of the Master Sword".

So, looking back at the series so far, we began knitting together the various elements. And then all sorts of contradictions arose". Despite these inconsistencies, the storyline established the Master Sword as a defining element of the narrative. The plot centres around Link transforming the weapon into the Master Sword. It gives Link the power to defeat the antagonist Demon King Demise by trapping his essence inside the sword. This storyline was the foundation for the lore of every other title in The Legend of Zelda series, with the Master Sword placed at the heart of its mythology. The sword was also used as the central game mechanic for the Wii version of Skyward Sword. A television commercial for the game's release in 2011 prominently featured the Master Sword as a way to connect the player to the game's motion controls, which involved using the Wii MotionPlus to control the sword's movements on screen.
