Ephemer

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.

Before Kingdom Hearts χ
Ephemer becomes a Keyblade wielder at an unknown point. Shortly afterwards, Ephemer meets Skuld and joins her party. Over time, more wielders gradually join them as their journey to gather Lux. Due to their busy schedules, however, Ephemer and Skuld begin drifting apart, putting a strain on their friendship. Eventually, Ephemer decides to leave the group to go his own way.

Ephemer starts to question the secrets of the world and the Book of Prophecies. Seeking answers, Ephemer approaches Foreteller Ava and asks her why the Unions compete against each other rather than working together, and Ava explains that it is simply because the Master of Masters arranged for things to be this way between the Unions.

Kingdom Hearts χ[chi]
Ephemer meets Player one day while in Waterfront Park, where he is bested by an Invisible and Player steps in to help Ephemer defeat the Invisible. Ephemer then introduces himself to Player, and the two find that they are from opposing Unions. In spite of this, Ephemer reveals that he is investigating the truth behind the Book of Prophecies and why the Unions compete against each other for Lux.

When Player tells Ephemer about a dream of they had the night before, where the Foretellers met with a hooded figure in the Foretellers' Chamber, Ephemer suggests that they investigate the Foretellers' Chamber located in the Clock Tower. Discovering an entrance in the sewers, Ephemer and Player attempt to sneak into the Clock Tower, but are mobbed by Heartless along the way. A crashing noise from ahead prompts Player to proceed forward, but Ephemer persuades them that they should continue their investigation the following day since it would suspicious if their Union leaders notice that they were missing for too long.

Sometime later, Ephemer comes across a depressed Ava sitting alone in the Fountain Square and inquires her about her troubles. Although Ava remains vague, she expresses her doubts about the Master's teachings regarding the competition between the Unions, much to Ephemer's surprise. Ava approves of Ephemer's desire to solve the mysteries of the world, as she believes that people should question things and think for themselves. Ephemer jokingly tries to get Ava to talk about the Book of Prophecies, but she denies him. Ephemer reveals to her that he had befriended a Keyblade wielder from a different Union, and Ava is pleased that wielders from other Unions could work together. Before Ephemer leaves, he asks Ava to cheer up, which brings a smile to her face.

Later that night, Ephemer ventures into the sewers alone to continue his investigation without Player. Before Ephemer can enter the Clock Tower, however, he is confronted by Ava. Relocating to the outskirts of Daybreak Town, Ava divulges the final entry in the Book of Prophecies, which details the events of the Keyblade War that will subsequently bring about the end of the world, and invites Ephemer to join her Dandelions to ensure the future of the light. Although skeptical, Ephemer agrees, and Ava proceeds to explain that she intends on choosing five people from the Dandelions, including Ephemer, to act as Union leaders in the Foretellers' stead after the Keyblade War. When Ephemer expresses his reluctance about being a Union leader, Ava implores Ephemer to rise up to the challenge alongside his fellow Union leaders and provides Ephemer with a book of rules that must be followed once the new Union leaders take charge to prevent future destruction. Additionally, Ava informs Ephemer that the Union leaders must erase the memories of the Keyblade War from their fellow Dandelions and avoid any possible connections between the two worlds, thus the truth about the Keyblade War must be kept a secret among the new Union leaders. In spite of his doubts, Ephemer accepts this task. Ava then sends Ephemer to travel to another realm in preparation for what is to come, instructing him to meet the other Union leaders in the Keyblade Graveyard following the Keyblade War.

From this other realm, Ephemer attempts to reach out to Player by showing them his conversation with Ava in a dream. From there, Ephemer meets Player in the Fountain Square as they were originally meant to and apologizes for being late before they head to the sewers. However, when Player becomes uneasy, Ephemer tells Player that he will be waiting for them and disperses into a cloud of dandelions. Around the same time, Ephemer visits Skuld in a dream as well and tasks her to seek out Player, informing her that the end of the world is near.

When the Dandelions cross over to the new world, as per Ava's instructions, Ephemer is reunited with Skuld, who had accepted Ava's invitation to join the Dandelions. They venture back to the Keyblade Graveyard following the conclusion of the Keyblade War and find Player unconscious on the battlefield. When Player awakens, Ephemer happy reunites with Player and have them become a member of the Dandelions. Ephemer and Skuld bring Player to the new world, where their memories, along with the memories of the other Dandelions, are erased upon arrival.

Kingdom Hearts Union χ[Cross]
As per Ava's instructions, Ephemer goes to the Keyblade Graveyard. Though Ephemer looks around, he can't see anyone else - finding that he is the first of the five new Union Leaders to arrive. Just then, a voice rings out from behind him, asking if they are they second. Turning, a shocked Ephemer sees Skuld - who asks if Ephemer is disappointed to see that it's her, mentioning that she'd anticipated seeing him there. Ephemer reminisces about how the two of them had already visited the Keyblade Graveyard together since the end of the Keyblade War, however he didn't think that she'd be chosen as one of the Union Leaders. Skuld reasons that it's in part because the identity of the Union Leaders was meant to be kept secret until they all met at this moment. Skuld then wonders aloud who the other three Union Leaders could be - but Ephemer admits that he has no idea - admitting that, before Skuld showed up, he hadn't put much faith in what Ava had said, so he couldn't possibly think of who could be coming. Skuld then sees someone in the distance.

When the third Union Leader gets closer, Skuld welcomes him and introduces herself, while Ephemer asks if he'd been sent by Ava as well. The third confirms this, prompting Ephemer to step forward in order to shake his hand, introducing himself in the process. The third then introduces himself as Ventus, though he asks that Ephemer and Skuld call him Ven. While bonding, Ephemer and Skuld reveal that they had been friends prior to becoming Dandelions. Ven admits that he's sort of jealous of their relationship because he's always been kind of a loner; something which Skuld can relate to. However, Ven claims not to be anyone special either, as he'd never ranked very high, so really he's not sure why he was chosen to be one of the new Union Leaders. Skuld conveys that Ava must have had some reason for choosing Ven - though Ven explains that he'd never really spoken to Ava before so he doesn't know what she was like. Ephemer pipes up, saying that Ava was really easy to talk to - amused Skuld tells Ephemer that he thinks everyone is easy to talk to; though he denies it. Ven voices his jealousy over Ephemer and Skuld's friendship - but Ephemer corrects Ven by stating that he's their friend now too.

With that, the fourth Union Leader makes his presence know, commenting on how nice the concept of friends sounds and introducing himself as Brain. Brain admits that he'd thought he would be the last to arrive - though surprisingly this isn't the case. When Ephemer confirms this, Brain asks if Ephemer is their leader - though Ephemer denies that he is the leader and stresses that it hasn't been decided yet, as they first must wait until they've all arrived. Brain accepts this, asking instead if the rules they'd been provided were absolute. Skuld suggests that the rules would be absolute, prompting Brain to compare her to Ava because of her diligence; which she notes is the second time that's happened. Hearing this, Ephemer jokes that Skuld isn't as amazing as Ava. Brain then questions if they can really believe all of this - voicing his discomfort with lying to everyone about the Keyblade War; something that had bothered Ven as well. Thinking about the pain that Player endured because of the Keyblade War, Ephemer firmly states that it must remain a secret, as he doesn't want people to remember the tragedy they'll follow the rules. Brain, Ven and Skuld all accept this, stating that they all believe in Ephemer. Together, the four new Union Leaders await the arrival of their final comrade.

Later, in Daybreak Town, Chirithy reports to Ephemer and Skuld about Player's persisting nightmares. Though Chirithy felt guilty about lying to Player initially, he really does want to allow Player to forget. Skuld asks that Chirithy push through it, which Chirithy agrees to do, because Player is his best friend. Ephemer then states that, for Player's sake, he leaves what he'd told Chirithy earlier about the Union Cross up to him. Skuld adds that surely Player's tragic memories within his Heart will be worn away as he goes on adventures with his friends. Unexpectedly, Ephemer mentions that he also senses a different Darkness in the world from that of the old one, being more complex - so he doesn't fully understand it himself - but he senses a strong intention. Skuld interjects however and advises Chirithy to leave it to them and focus on taking care of Player. Once Chirithy has gone, Skuld asks why Ephemer told Chirithy about the darkness, as they likely just made Chirithy worry. Ephemer apologizes, arguing that it affects Chirithy as well, and that the more that the new world differs from its predecessor, the more uneasiness will be generated. Furthermore, the Union Cross results in Ephemer sensing a different kind of malice and Darkness. Skuld then reminds Ephemer that the rules dictate that they start the Union Cross - which Ephemer accepts, suggesting that they'll just have to let their Heart's be their guiding keys.
