Editing Xehanort

Finally completing his tour and with newfound purpose and ambitions, Xehanort returned to Scala ad Caelum and stated his beliefs to Eraqus that the world needed to be restructured and that it would take several lifetimes, wishing to extend his life to recreate the world and then experience it himself. Eventually, both Eraqus and Xehanort passed their exams and became [[Keyblade Master]]s, and Eraqus was chosen as the Master's successor of Scala ad Caelum and given the [[Master's Defender]]; Xehanort was chosen to inherit the [[No Name]]. The newly titled Master Xehanort was free to take on apprentices of his own to train, and travel the worlds freely. Xehanort decided to dedicate the remainder of his life to studying the Keyblade War and Kingdom Hearts in an effort to summon it once more in order to purge the worlds and remake them. This caused friction with Eraqus, who attempted to stop Xehanort while he was leaving Scala. Though the exact contents of the fight are unknown, Xehanort succeeded in leaving Scala and journeyed throughout the worlds for years in pursuit of knowledge and further power.

Shaving his head as a demonstration of his resolve and now firmly associated with darkness, Xehanort journeyed and obtained vast knowledge concerning Keyblade lore, the Heartless, and the mysteries of the [[Keyblade War]], and Kingdom Hearts. He met other powerful individuals, including a fellow Keyblade Master, [[Yen Sid]], who became a close friend of Eraqus and was weary of Xehanort's ambitions for further knowledge and power. Over the years, Xehanort's beliefs that darkness and light were meant to be in balance were further reinforced, believing that the "tyranny" of light had destroyed much of the darkness and shifted that balance. He, therefore, resolved to obtain the power of Kingdom Hearts so that he may create a World in balance. To that end, he sought to recreate the legendary [[χ-blade]] and begin a new Keyblade War. By this time, however, Xehanort had grown very old, and he devised a plan to use his Keyblade to extract his own heart and transfer it to a younger body to prolong his life until his ambitions were fulfilled. At one point, Xehanort discussed his ideas about the Keyblade War with Eraqus, who attempted to dissuade him from risking a new apocalypse for the sake of gaining knowledge. When Eraqus tried to stop him by force, Xehanort used his power of darkness to easily fend him off.

Four years later, Master Eraqus invites Master Xehanort to the Land of Departure to witness Terra and Aqua becoming Keyblade Masters. Xehanort accepts, but he hints that Terra has the potential for darkness and suggests Eraqus administer a [[Mark of Mastery exam]] to the two apprentices. During the exam, Xehanort subtly uses darkness to affect the [[Orb of Light|Orbs of Light]] and nudge Terra's darkness during his spar with Aqua. At the end of the exam, Eraqus names Aqua as Master, telling Terra that he failed to keep his darkness in check. Meanwhile, Xehanort leaves the building, passing by Vanitas, who tells him that Terra is the key to luring Ventus away from home. Outside, Xehanort tells Terra that he should not fear his darkness, and that he should learn to channel it instead. He then leaves via a [[Corridor of Darkness]], making himself unavailable when Eraqus tries to contact him about the [[Unversed]] threat. Master Eraqus tasks Aqua and Terra with countering the Unversed and locating Master Xehanort, and Vanitas manipulates Ventus into following Terra.

Later, Master Xehanort has Vanitas abduct [[Mickey Mouse]] to lure Ventus to the Keyblade Graveyard, where he reveals to Ventus the truth about his past and his plans to create the χ-blade. He adds that Master Eraqus has kept Ventus from venturing away from the Land of Departure in order to prevent the creation of the χ-blade, and that he never trusted Ventus enough to tell him the truth. Xehanort summons a dark vortex that sends Ven to the Land of Departure, expecting him to confront Eraqus. He then calls Terra to him, telling him that Ven went to confront Eraqus on his own, and that he fears for Ven's safety. He sends Terra after Ventus, and Terra arrives in time to protect Ven, throws him through a portal to safety, and defeats Eraqus in battle. Although Terra and Eraqus both regret their actions, Xehanort appears and delivers the final blow against Eraqus, who dissolves into light in Terra's arms. Revealing his true intentions to Terra, for him to succumb to darkness, Xehanort tells Terra to return to the Keyblade Graveyard, where he will see Ventus and Aqua meet their ends. He then summons his Keyblade and uses it to unleash darkness on the Land of Departure, completely destroying the world and leaving nothing but the castle's remains, before departing.

Terra, Ven and Aqua arrive at the Keyblade Graveyard, where Master Xehanort and Vanitas confront the three Keyblade wielders. Xehanort uses his immense magic to alter the landscape, summoning giant cliffs and creating a whirling stream of abandoned Keyblades that pursues the three friends. Terra is knocked onto the cliff where Xehanort stands, Ventus tries to attack him from behind, but Xehanort instantly moves behind Ven and grabs him by the helmet of his Keyblade Armor. Terra is knocked off the cliff by the flying Keyblades while Xehanort flash-freezes Ventus and drops him off the cliff. Xehanort then creates an orb of magic which he launches into the clouds overhead, summoning Kingdom Hearts in the sky.

{{Q|You are just one of many roads that I might choose to take.|Master Xehanort to Terra}}

Master Xehanort and Terra continue to dispute over internal dominance within Terra-Xehanort. Despite Xehanort's insistence that he will soon subsume Terra's heart into his own, Terra remains confident that he will win over and eventually expel Xehanort. Xehanort realizes that Terra is harboring the heart of Eraqus, which may allow him to resist his darkness for longer than he expected. However, Xehanort serenely points out that he has many other plans in the works should he lose control over Terra's body.

Master Xehanort arrives, admitting using [[Ventus-Vanitas|only two hearts]] to create the χ-blade was too hasty. He reveals the χ-blade was divided at the conclusion of the Keyblade War into thirteen darknesses and seven lights. To gather the amount of hearts he needed, he tricked Maleficent into gathering [[Princesses of Heart|the seven pure lights]] and created the Organization to hold pieces of his heart to serve as the thirteen darknesses. Due to Sora and Riku's interference and the unforeseen independence or weakness of a number of Organization members, the two-part plan had failed. However, having given Young Xehanort the ability to travel through time, Xehanort has brought about the creation of a new Organization XIII made up of himself, his other incarnations, and vessels that harbor pieces of his heart, which he intends to pit against the "Seven Lights".

Xehanort moves in to place a fragment of his heart inside Sora, but the arrival of [[Lea]], [[Donald]], and [[Goofy]] stalls the Organization long enough that they are forced to retreat, each member returning to his own time. As Master Xehanort fades, he tells his opponents that both the seven of light and the thirteen of darkness will have their numbers filled when the time comes.

Once all the seven guardians have been found they travel to the Keyblade Graveyard where Xehanort waits. He appears alongside Ansem, Xemnas, Vanitas, and his younger self, giving a similar speech to the one he gave Eraqus many years ago. The group summons a massive horde of Heartless, Nobodies, and Unversed to stall the guardians before departing.

Once the guardians make it back to the Keyblade Graveyard, Xehanort and the rest of the real Organization XIII confront them at the crossroads where he once confronted Terra, Aqua and Ventus. He states that the secrets of the Keyblade War will finally be unlocked, then summons [[No Name]] and creates a sprawling labyrinth known as [[The Skein of Severance]] as the battleground for the final clash, signifying the beginning of the war. Xehanort himself remains on a larger pillar behind the labyrinth to observe the coming battles.

Unbeknownst to the guardians, Xehanort takes seven fragments of Kairi's surviving heart and scatters five of them across Scala ad Caelum, having hidden the remaining two within the hearts of Riku and Mickey, all as a final resort to ensure Kingdom Hearts can be opened through the power of the [[Princesses of Heart]]. During this time, Xehanort encounters a future version of Sora, who has used the [[power of waking]] to travel from the past and restore Kairi's heart. Noticing that Sora is beginning to fade from existence as a consequence of his power, Xehanort taunts that Sora has nearly run out of time as his present counterpart arrives with Donald and Goofy. {{storylink|Kingdom Hearts III Re Mind}}

After Sora defeats the [[Replica Xehanort]]s, Xehanort appears again and explains that Scala ad Caelum used to be the seat of power for all Keyblade wielders, and that he and his other selves can reunite here. Xehanort proceeds to absorb the replicas, granting him a set of [[Keyblade Armor]]. Summoning No Name, he proceeds to reshape the world to trap Sora, Donald, and Goofy, and engages them in battle. After a grueling battle both within the town and under its waters, Xehanort's armor is destroyed, but he escapes through a Corridor to the peak of the town. Sora, Donald, and Goofy pursue him to the tower, where he summons the χ-blade, summons Kingdom Hearts once again, and challenges the three to a final battle. Eventually, Xehanort uses the power of both Kingdom Hearts and the χ-blade to nearly slay Sora, but he is called back by Donald and Goofy. Together, they use the Keyblade and the power of friendship to break through Xehanort's attack and deal a blow that pierces Xehanort through the chest, mortally wounding him.
