KINGDOM HEARTS χ BACK COVER

First Appearance: KINGDOM HEARTS χ[chi] (2013)
Japanese voice actor: Tomokazu Sugita
English voice actor: Ray Chase

The teacher of the Foretellers, author of the Book of Prophecies, and creator of the Chirithy. The Master is playful, irreverent, and to be honest, a little unnerving. But while his personality may not lend itself to the idea of a wise leader, he is held in high regard and his teachings are treated as absolute. 

The Master bestows each of his six apprentices with new names and a special role for the events to come.

To Ira, to lead the other Foretellers and maintain his teachings in the event of the Master's absence.

To Aced, to support Ira as his second-in-command and ensure he stays on the right path. Should he deviate, Aced is to take his place.

To Invi, he gives the role of mediator. He tells Invi to look after the group and to keep the peace between unions.

To Gula, the Master gives a page that doesn't exist in the Foretellers' copies of the Book of Prophecies. This page outlines details of a traitor to the group - and it becomes Gula's duty to figure out who will betray them all.

To Ava, he gives the role of finding exceptional Keyblade wielders, regardless of their Union, and recruiting them to a new organization. This group will escape the impending darkness of the Keyblade War in order to keep the light alive. The Master gives Ava a list of candidates who will succeed the Foretellers as heads of the Unions when the war is over, circling one name in red. This one, he explains, is to be given their own Book of Prophecies.

The Master gives these five apprentices copies of the Book of Prophecies and tells them to establish separate Unions of Keyblade Wielders so that they may maintain the balance of light and darkness. 

To his final apprentice Luxu, he bequeaths the No Name Keyblade and instructs him to pass it on through a line of successors. This Keyblade is embedded with the Master's eye that is capable of looking into the future, allowing him to witness events as they unfold and making it possible for him to compose the Book of Prophecies. The Master advises Luxu to stay out of sight and merely watch everything that occurs. Then, he gives him a large black box with orders to never open under any circumstances, and sends him on his way.

After this, the Master vanishes, leaving behind nothing but his lingering influence.
