Ephemer

Ephemera is a Keyblade wielder introduced in Kingdom Hearts χ. He has a desire to know the truth behind the gathering of Lux and the structure of the World.

Kingdom Hearts χ
While in Daybreak Town, the Player finds Ephemera battling an Invisible. The player runs to Ephemera's aid following the defeat of the Heartless, and they introduce themselves, finding each other to be in rival Unions. Ephemera notes how he feels that it is fate that they have met each other, and to thank the Player, Ephemera reveals some information. Ephemera reveals that the Lux that the Player and other Keyblade wielders have been tasked to collect do not belong to the worlds, but to Daybreak Town, and that the many worlds they've been visiting are merely illusions. He also reveals that it's impossible to go through the whole world to collect Lux, so a non-existent world was created to facilitate gathering light from those places. He believes that the source of the illusory worlds are the Book of Prophecies that the Union's Foretellers possess. The Player then recalls a dream where the Player witnessed the Foretellers speaking to a mysterious unknown, and mentions this dream to Ephemera, who decides that they should investigate together.

Ephemera and the Player fight Heartless in the sewers on the way to the location from the Player's dream, but they return early because Ephemera considers it too dark to move on. The next day, Ephemera lights up the way with a candle, the Player follows him. Then, Ephemera protects the candle while the Player clears out the way for him. At one point, Ephemera wants the Player to check out the way for Heartless. The Player does so and encounters an Invisible which the Player battles. The Player appears to be losing the fight when Ephemera jumps in and defeats the Invisible, saying that he and the Player are even now. The ground then appears to be shaking for a moment, then Ephemera and the Player continue their path. Just before they reach their destination, Ephemera holds the Player back. He tells the Player that they should head back for today because they took too long in that place. He also says that skipping Union Missions for too long would rise suspicion, and since they have secured their route already, they should investigate on the next opportunity. To that, the Player agrees and Ephemera says that they are friends beyond Unions. They head back, however, in the night, Ephemera goes back to the place where they stopped, he says sorry to the Player and then goes in. On the next day, Ephemera is nowhere to be seen for the whole day although the Player waits until evening for him.
