A young and outgoing Keyblade wielder. He questions the way the world works and decides to solve its mysteries on his own.
"We'll go together."

Ephemer is a Keyblade wielder who appears in Kingdom Hearts χ. He seeks to discover the truth behind the gathering of Lux and the structure of the World.


Kingdom Hearts χ[edit]

Ephemer is a member of a different Union than the Player.[1] When he first meets them, he reveals that the Lux the Player is tasked with collecting from the various worlds truly belongs to Daybreak Town. He also claims the worlds the Player has visited up to this point are actually illusions created by the Book of Prophecies each Foreteller possesses. After the Player tells Ephemer about a strange dream they had about the Foretellers and a mysterious figure[please confirm], the Keyblade wielder decides to team up with them and investigate this matter.

Together, Ephemer and the Player dispatch several Heartless as they make their way towards the Foretellers' headquarters. The two ultimately decide to abandon their investigation, and soon afterwards, Ephemer mysteriously disappears. Some time later, the Player has a dream about Ephemer in which the Keyblade wielder asks Foreteller Ava to divulge the secrets of the Book of Prophecies. Ava refuses.

The next day, Ephemer reunites with the Player in their dreams. The two briefly resume their earlier investigation. When the Player awakens, they learn in a conversation with Foreteller Ava that Ephemer may be in another dimension and is possibly using dreams to communicate as he closes in on a hidden truth.

When the Player meets an enigmatic Keyblade wielder named Skuld, she reveals that Ephemer is from her Union and seems to have changed. Skuld claims Ephemer is also appearing to her in her dreams; in one, she reveals, he tells her the World is nearing its end.


Ephemer has curly, silver hair and blue eyes. He wears a white shirt under a black vest, dark grey pants, and black boots. He has a red scarf around his neck.

"Ephemera" refers to things that are short-lived or transitory.
