{{Q|I am no longer a Master. I doffed that mantle.|Yen Sid to Terra.}}

'''Yen Sid''' is a powerful sorcerer introduced in ''[[Kingdom Hearts II]]'', and originally taken from the "{{w|The Sorcerer's Apprentice#Fantasia|The Sorcerer's Apprentice}}" short in the Disney film ''{{w|Fantasia (1940 film)|Fantasia}}''. He is a retired [[Keyblade Master]], renowned for his wisdom and command over the arts of magic. Although he is no longer an active Keyblade Master, he still keeps a close watch on the balance between [[light]] and [[darkness]]. He was once [[Mickey Mouse]]'s master, and taught him everything he knows of magic and the Keyblade.

 

Yen Sid was once a Keyblade Master alongside [[Eraqus]] and [[Xehanort]].<ref>'''''[[Kingdom Hearts Birth by Sleep]]''''', '''Yen Sid''': "There was a time when I walked the path of the Keyblade Master alongside Eraqus and Xehanort. But the three of us have gone our separate ways."</ref> He chose to retire to the [[Mysterious Tower]] and lay down his Keyblade Master mantle, but remained a powerful sorcerer and continued to observe the balance between light and darkness. He also hoped Xehanort would let go of his fascination with the [[Keyblade War]] and the [[χ-blade]]. {{storylink|Kingdom Hearts Birth by Sleep}}

 

Yen Sid took on the boatman [[Mickey Mouse]] as his apprentice, teaching him everything he knows about magic and the Keyblade. At one point, he sent Mickey on a mission to the [[Country of the Musketeers]].{{storylink|Kingdom Hearts 3D: Dream Drop Distance}} However, Yen Sid was unable to give Mickey a [[Mark of Mastery exam]]. After saving [[Princess Minnie]], Mickey had decided to end his training and instead focus on being king of [[Disney Castle]]. {{storylink|Kingdom Hearts Birth by Sleep}}

Yen Sid had become aware of the presence of the [[Unversed]] threatening the worlds, just as his former apprentice Mickey had. Mickey returned to Yen Sid to complete his training as a [[Keyblade Master]]. Believing [[Eraqus]] and [[Xehanort]] could use the help of another Master, Yen Sid resumed completing Mickey's training. However, after Mickey failed his first test, Yen Sid told him of feelings of dread he had; something terrible would occur soon. The next day, Yen Sid contacted the [[Land of Departure]] to warn Eraqus of the threat and to send his pupils out to quell the chaos. Mickey decided to assist without permission and stole a [[Star Shard]] to travel the worlds; because Mickey did not fully understand how it worked, Yen Sid remained unable to track him as the shard randomly sent Mickey around the worlds.

When [[Terra]] visits [[Mysterious Tower|Yen Sid's tower]], he asks him for guidance about [[Master Xehanort]], [[Vanitas]], and the Unversed; Yen Sid advises Terra to treat all three as the same problem. After Terra leaves, Yen Sid muses on his disappointment in Xehanort's continuing folly. Later, [[Ventus]] shows up at his tower with a [[Star Shard]], and Master Yen Sid uses divination magic to locate Mickey. However, unforeseen interference prevented Ventus from returning with Mickey. [[Aqua]] later returns Mickey to his tower, and Master Yen Sid tells her of Master Eraqus's destruction and that the murder was committed by Terra and Master Xehanort. Sometime after Aqua leaves for the [[Keyblade Graveyard]], Mickey departs to assist her and her friends.

Following Vanitas's defeat, Mickey returns with Aqua and a comatose Ventus. Master Yen Sid finds himself unable to sense Ventus's heart and encourages Aqua to believe in their friendship, which serves as the key to bring him home one day. Some time later, Mickey sorrowfully hands in the Star Shard and [[Star Seeker|his Keyblade]], thinking he has failed his Mark of Mastery exam and disgraced his master, and prepares to depart. However, Master Yen Sid gives him back the [[Keyblade]], showing that Mickey, in fact, passed and became a Master.

After discovering that Sora has the power to save all the lost hearts connected to him, Mickey meets with Yen Sid to discuss their ongoing search for Terra, Ventus, and Aqua. However, Yen Sid shocks Mickey by revealing that the destruction of [[Ansem, Seeker of Darkness|Ansem]] and [[Xemnas]] has led to the return of [[Xehanort]], and not just a "single one" of him, and which will eventually lead to the return of Master Xehanort. Yen Sid had known that this disaster might come about while he was mentoring Sora, but chose not to disclose it to anyone because leaving Xemnas alive was not an option.{{fact}}<!--cite to the ULTIMANIA, use the actual quote. See the x-blade, Xehanort's Keyblade, or Keyblade of People's Hearts pages for examples <ref>[http://www.kh2.co.uk/kingdom-hearts-recoded/news/kh-recoded-ultimania-nomura-interview-scenario.php Nomura discusses Xemnas and Master Xehanort in ''Re:coded'' Ultimania]</ref>--> As Mickey, the sole surviving Keyblade Master, will not be enough to counter Xehanort's new threat, Yen Sid orders Mickey to summon Sora and Riku to him to undertake the [[Mark of Mastery exam]].

Yen Sid explains the full history of Master Xehanort to Sora and Riku and puts them through the Mark of Mastery exam by assigning them to awaken several worlds which remained in the [[Sleeping Worlds]] following Ansem's destruction to obtain the power of waking, and explains numerous facts such as the nature of the [[Dream Eater]]s and residents of the sleeping worlds. However, soon after the exam begins, Yen Sid starts to feel that something is going awry.

 

 

 

 

 

 

 

 

 

After Kairi awakens, Yen Sid is informed that Riku had gone to [[Quadratum]] to find Sora and halts a flustered Mickey from following him, aware that they were going into "uncharted waters" Knowing that Xehanort's clue came from during his time as a researcher, Yen Sid recalls hearing stories of the ancient Keyblade Masters crossing over into another world and believes Xehanort might have studied it.  

He sends Donald and Goofy traveling to the Land of Departure, Twilight Town, and Radiant Garden to inform their friends about what they discovered; approves of Kairi's idea of continuing her training under Aqua, and tasks Mickey with discovering the connection between the ancient Masters and the new world, suggesting to begin his search in Scala ad Caelum.

Master Yen Sid is a rather severe-looking old man with long, grey hair, bushy eyebrows, and a long, grey beard that parts down the middle. He wears the famous, conical sorcerer's hat on his head. The hat is blue and decorated with several yellow stars and a yellow crescent moon. ''Fantasia'' shows that the top of Yen Sid's head is bald under the hat, though he never removes it in the ''Kingdom Hearts'' series. He wears long, billowing blue robes with sky blue lining, with the insides of his robes being dark red. The whites of his eyes are quite large in comparison to his small pupils, something that is further highlighted by the fact that his eyes are often wide open. In ''Kingdom Hearts Birth by Sleep'', there are very small changes to the sorcerer's robes, such as the sky blue lining becoming thicker and the robes themselves being a bit wider.

Yen Sid is seen to wear black shoes in his ''Birth by Sleep'' character model. In ''Kingdom Hearts III'', full black boots can be seen for a brief moment when his robe billows from Yen Sid releasing the wall of light magic.

While little is known about his life as a Keyblade master, the elderly sorcerer is shown to be a rather stern man. In almost every instance, he is shown to be frowning. But beneath his harsh exterior belies a man who strongly believes in his apprentices no matter how much mischief they may get up to, demonstrated by when he expresses annoyance at Mickey for running off with the Star Shard and recklessly getting lost with it, but then forgives Mickey and awards him the title of Master with an encouraging smile. Despite his outwardly gruff nature, he has displayed a sense of humor, shown when he cracks a smile and points out in a friendly manner how small Sora's clothes have gotten.

Given his past status as a Keyblade master, he is shown to have great knowledge about the properties of the Heart, the Heartless, the Nobodies, the Unversed, and the Dream Eaters. It is he who explains the nature of the Unversed to Master Eraqus, and that of the Nobodies and the Dream Eaters to Sora, Donald and Goofy, and also tells them that as long as darkness exists in one heart, the Heartless will never cease to exist. So powerful and wise is he, that even Terra, Aqua, and Ventus speak to him with utmost respect, despite him not being their master. However, Mickey and Riku merely refer to him as "Yen Sid" without calling him "Master", possibly because they, like Master Eraqus, are also Keyblade Masters (though this is only in the English versions; in the Japanese versions, they still call him "Master Yen Sid" as a sign of respect).

Master Yen Sid is a master of the magical arts, able to perform powerful magic spells comparable to [[Merlin]]'s. He has shown the ability to teleport, even between worlds, create illusions while training Mickey, and create cosmic smoke to locate a person. He seeks counsel with the stars to predict the conditions of the present and the future, which allows him to gather information about the worlds' condition and to pass it on to his allies.

He has also shown the ability to manipulate and utilize the power of light to an extraordinary extent, as demonstrated at the Keyblade Graveyard, being able to part an immense army of Heartless with a mere gesture of his hands and hold them off long enough to allow the guardians of light to advance through them without any exertion.

He has also shown the ability to manipulate time to an extent, at least as it pertains to the Realm of Sleep, were the laws of time travel, as he is able to revert Sora and Riku back to younger versions of themselves and send them back to a point in time before Destiny Islands was destroyed in that realm for their Mark of Mastery exam.

 

As a retired Keyblade Master, he presumably still retains the power to use the Keyblade, but does not appear to use it.

==Origin==

The great sorcerer first appeared in the ''Fantasia'' short ''The Sorcerer's Apprentice'' as Mickey Mouse's master. He was the owner of a magical hat that is apparently the source of his power. In the movie's most acclaimed sequence, Mickey steals the hat and begins to play with its magic. However, as he was warned by Yen Sid, the power of the magic cannot be controlled by Mickey and wreaks havoc. Yen Sid arrives and manages to stop the magical chaos with his own powers.
