Invi

Invi is a Keyblade Master who appears in Kingdom Hearts χ. As a Foreteller, she leads the Anguis Union and is an apprentice of Master of Masters.

Before Kingdom Hearts χ
Invi is given a Keyblade forged from her own heart by the Master of Masters, who takes Invi, Aced, Ava, Gula, Ira, and Luxu as his apprentices. Invi eventually achieves the rank of Keyblade Master alongside her fellow apprentices.

After the Master bestows a copy of the Book of Prophecies upon Invi, he grants her leadership over the Anguis Union as its Foreteller. As Invi and the other Foretellers read their copies of the Book of Prophecies, they are shocked by the final entry, which details an event known as the Keyblade War, during which light would expire and the world would reach its end.

When Luxu leaves to fulfill his role assigned to him by the Master, the Foretellers are shocked by his sudden disappearance. Shortly thereafter, the Master meets with Invi alone in the Foretellers' Chamber and assigns her role: to observe her fellow Foretellers. The Master instructs Invi to be impartial in the affairs of the Foretellers in order to act as a mediator. Invi voices her concern over having to form and maintain their own Unions without the Master or Luxu to guide them, but the Master assures Invi that change is necessary for things to progress forward and advises her to let her heart guide her down the right path

Invi and her fellow Foretellers are soon introduced the Master's latest creation, the Chirithy. Though the Spirit Chirithy are meant to aid Keyblade wielders in their endeavors, the Master warns them that if a wielder falls to darkness, so will their Chirithy, causing them to transform into a Nightmare.

Without warning, the Master disappears from the world, and although the Foretellers actively seek him out, they are unable to locate him. Upholding the Master's teachings, the Foretellers begin recruiting Keyblade wielders to each of their Unions, utilizing the powers of their copies of the Book of Prophecies in the form of Medals to aid their wielders in collecting Lux in order to maintain the balance of power.

Kingdom Hearts χ[chi]
Having watched Player defeat countless Heartless throughout Daybreak Town, Invi commends their abilities. Invi offers Player advice on defeating larger Heartless, suggesting that they fight alongside the other Anguis Union members and then leaving them to defeat a Darkside. After the Darkside is defeated, Invi reappears and warns Player that there are others who collect light for nefarious purposes. Invi allows Player to discern who walks the path of darkness before she departs.

When Mickey Mouse arrives in Daybreak Town via Star Shard with Chip and Dale in search of Donald and Goofy, he notes that the Star Shard did not guide him there, remaining unaware that Invi is watching him from a nearby rooftop.

The Foretellers take notice of the Keyblade wielders utilizing bangles that provides them the power to collect dark energy. Ultimately, the Foretellers decide using the bangles was acceptable for their Union members. Not long afterwards, Ira summons the Foretellers for a meeting in the Foretellers' Chamber, declaring that there is a traitor among them after discovering a Nightmare Chirithy snooping around their home. When Gula proposes to have each of the Foretellers summon their Spirits to prove their innocence, Invi points out that Gula's solution is not viable since it would be easy for any of them to summon a Chirithy that isn't a Nightmare. Ava proposes that the Nightmare could belong to a wielder in one of their Unions instead, but Ira reasons that the bangles are the Nightmare's doing and that only one of them could have obtained the bangles, thus the traitor has to be one of the Foretellers. However, Invi disagrees with Ira's claims, citing that there is no evidence to support his theories. When Aced condemns Ira for spreading doubt amongst them, Invi silences him, prompting Aced to adjure the meeting. After the other Foretellers departed, Invi questions Ira's strange behavior, who then confides in Invi about the existence of the Lost Page, an entry depicting the events surrounding the traitor which has been excluded from the Foretellers' copies of the Book of Prophecies. As Ira believes the traitor is likely whomever is in possession of the Lost Page, Invi begins to wonder if providing the Lost Page to only one of the Foretellers was done intentionally by the Master. Invi promises to keep an eye on the others and reports their actions back to Ira.

When Neoshadows appear in Daybreak Town, Player joins three other Keyblade wielders in their efforts to quash the darkness being spread by the new species of Heartless; however, Player is the only survivor. After Chirithy witnesses another of his kind fade, Invi appears to speak with Player, revealing that while the Keyblade wielders are gathering Lux at an amazing rate, the darkness is spreading even faster. With this, Chirithy asks if that means that there really is a traitor among them, to which Invi states that she is not willing to believe that yet.

One night, Player is shown a dream by Chirithy, in which Invi and the other Foretellers meet with the Master in the Foretellers' Chamber, though Nightmare Chirithy quickly puts a stop to this dream.

A few days later, Aced asks to meet with Invi, Ava, and Gula in a warehouse to form an alliance between their Unions. When Invi arrives, Aced reveals his alliance with Gula and extends the offer to her as well, but Invi rejects him, seeing this as a defiant act in pursuit of power and accusing that Aced has been tainted by darkness. Conversely, Aced retorts that it is Invi who has been tainted by darkness, as she reports their actions back to Ira and could possibly be conspiring with him. With this, Invi parts ways with her fellow Foretellers.

When Invi reports back to Ira that Aced and Gula's alliance, Ira assumes that Aced is the traitor, though Invi argues that Aced's intentions indicate otherwise. As Aced is betraying the Master's teachings, Invi volunteers to persuade Gula to sever his alliance with Aced, believing that Ira's intervention will only make things worse. Furthermore, Invi mentions that Aced has begun to question their relationship, and as such, her reports to Ira will be less frequent.

After Player successfully completes the Dark Corridor Trials, Chirithy reports back to Invi, who is pleased to hear of their progress, but Chirithy questions the wisdom of assigning such a dangerous mission. Invi laments that she has no choice but to hasten Player's training, as she must strengthen their resistance to darkness as quickly as possible and obtain as many warriors as they can get on the side of light.

A few months later, Invi convinces Gula that his alliance with Aced is pointless, as the latter had yet to rally anyone else to his cause and there had been no incidents since Ira captured the Nightmare Chirithy. Soon after Gula dissolves the alliance, an enraged Aced attacks Invi for her interference. Invi tries to defend that she is protecting the balance of power as the Master ordered them to, but Aced remains adamant that they need to defy the Master's teachings to protect the world and create alliances against the looming darkness. Invi deems Aced to be the traitor and attacks him with her Keyblade. When Ava and Gula arrive at the scene and join Invi in her fight against him, Aced launches himself into a vicious battle with his former comrades, from which he barely emerges alive.

After Gula is nearly struck down by Aced, Ava takes Gula into hiding, with Invi being the only one made aware of their location. However, Invi divulges Gula's location to Ira, prompting him to confront Ava a few days later. Afterwards, Ava chides Invi for worsening the conflict between the Foretellers by divulging Gula's whereabouts to Ira. During their argument, Ava reveals that she is recruiting Keyblade wielders from different Unions in a secret location because that is the role she has been assigned by the Master. Invi apologies for her words and inquires about Gula and her confrontation with Ira. As Ava discloses Gula's plot to summon Kingdom Hearts by collecting Lux, Invi realizes that Aced and Ira are gathering light to maintain the balance, but worries that doing so will ultimately lead to the Keyblade War. Deciding that she will also collect Lux to maintain the balance of power, Invi advises that Ava do the same, as they must do whatever they can to delay the Keyblade War for as long as possible.

When the Keyblade War breaks out in the Badlands, Invi leads the Anguis Union into battle. When Invi encounters Player, she apologizes for dragging them into the war before engaging them in battle. Once the fight is over, Invi praises Player's Foreteller for having trained such a good wielder. Invi encourages Player to live on before she withdraws.
