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.

Appearance
Ephemera is a Keyblade wielder much like the other wielders in Kingdom Hearts χ. He wears a white shirt and black vest on top, and dark grey pants. He also wears black boots. He has a red scarf around his neck, as well, and silver hair. He is seen wielding an upgraded version of the Starlight Keyblade.
