In Magi: The Labyrinth of Magic and its sequel, the main party consisting of our protagonists—Aladdin, Alibaba, and Morgiana—are a tight-knit group (as seen in the gif above). However, their bonds go beyond that to a deeper level and represent a deeper concept in the series—the connection between the Magi, their chosen King Vessels, and the Household that support them.
Magi are special magic-users that possess near-limitless power, extended life-spans, and are capable of raising dungeons. They then select those who they believe are suitable to be kings and allow them to enter the dungeons, with those who manage to conquer them being recognized as King Vessels by the fact that they obtain a Djinn’s power, which is represented in a Metal Vessel. As the potential king gains loyal allies, the power of the Metal Vessel spreads out to them and links them together, forming a Household.
This concept existed as early as the first arc, when the antagonist Jamil, assumed that his destiny was to rule as king and that Aladdin would lead him into doing so. While he dies with his wishes unfulfilled, Aladdin, Alibaba, and Morgiana form their first bonds here and become the ideal representation of the concept.
Aladdin, the Magi
Aladdin is initially unaware of his role in the world until his encounter with antagonist Jamil. He only fully comprehends it during the Balbadd arc, when he gains immense knowledge courtesy of Solomon’s Wisdom—which essentially bestows a limited form of omniscience upon him when used. To this end, he chooses his friend Alibaba as his official King Vessel and supports him through the use of his Heat Magic and wisdom (as seen in the gif below).
Alibaba, the King Vessel
Alibaba originally sought riches to atone for the sacking of the Balbadd castle by his friend, Cassim, and planned on using Aladdin’s strength to do so. The bond they forged eventually lead to the two becoming friends. His brave and noble actions led to him gaining the approval and power of the Djinn Amon, unintentionally turning him into a King Vessel (as seen in the gif below).
Because of his rags-to-riches upbringing, Alibaba not only possess insight into the struggles of the common man, but also the knowledge befitting royalty. He treats people of all stations in life equally, something that Aladdin recognizes as the qualities of a good king and has earned him many friends and allies, such as Morgiana.
Morgiana, the First Household Member
Morgiana was once a slave owned by Jamil, who gained her freedom upon his death. Grateful to both Aladdin and Alibaba, she decided to accompany them and became a close friend to the both of them. As a member of the Fanalis tribe, she has great strength, speed, and durability, which she utilized to assist them during the Balbadd arc of the story (as seen in the gif below).
Later on, in a different dungeon, she wishes for the strength to support Alibaba and Aladdin further. Amon recognizes her loyalty to them and grants her a portion of the power that he possesses, making her the first member of Alibaba’s Household. She uses it in combination with chains that she wraps around her wrists or ankles in order to expel flames and fly, becoming their wings when they cannot carry themselves (as seen in the gif below).
Conclusion
As the series progresses, we see others who share a similar bond that these three have. But few of them are as well-balanced or definitive, such as Sinbad possessing a large Household but no Magi, or Judar working with Hakuryuu but lacking a true Household to support him. In light of this, the main trio are the ideal combination and are likely to best serve as a cornerstone of the world.
