After being saved by Ephemer and Skuld following the conclusion of the Keyblade War, Player is brought to another realm, where the Dandelions have assembled as per Ava's instructions. Upon entering this new realm, however, everyone loses all their memories of their previous world, with the exception of the five wielders chosen to become the new Union leaders.
Following Ava's orders, Ephemer ventures to the the Keyblade Graveyard as one of the new Union Leaders. Soon, Ephemer is joined by Skuld, the second of the new Union Leaders, much to his surprise. When Skuld questions the whereabouts of other three Union Leaders, Ephemer admitted that, before Skuld showed up, he had his doubts about becoming a Union leader. Ventus, the third Union Leader, arrives and Ephemer and Skuld welcome him. While waiting for the fourth Union leader to appear, Ephemer and Skuld bond with Ventus, who is bewildered as to why he was chosen to become one of the new Union leaders. He admits that he is a little jealous of Ephemer and Skuld's friendship, though they assure him that they consider him a friend as well. Amused by the concept of friends, the fourth Union Leader appears and introduces himself as Brain. When Ephemer confirms that Brain is not the last to arrive as he had anticipated, Brain asks if Ephemer is meant to be their leader. Ephemer denies this, feeling as though they should wait until all of them are together to decide who leads. Brain then asks if the rules Ava provided are meant to be absolute, as he has issue with the concept of lying to the Dandelions, something which Ventus relates to. Thinking about the pain that Player had endured because of the Keyblade War, Ephemer firmly states that they are to follow the rules and that the truth about the previous world must remain a secret so that no one has to remember the tragedy of the Keyblade War. 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.
Player resumes his missions, initially reliving through the events leading up to the Keyblade War, and later making use of the newly created Union Cross, joining a party of fellow Dandelions and traveling to new worlds. Soon, Player has a nightmare in which he sees himself collapsed after the events of the Keyblade War. Furthermore, they relive their battle with Aced from just before the fated battle. Upon their defeat at Aced's hand, Player is jolted awake and Chirithy, concerned of the frequency of Player's nightmares, advises them to rest. As Player accepts this and warily returns to sleep, Chirithy bids them goodnight and continues to watch over them.
Prior to the Keyblade War, Strelitzia, another member of the Dandelions, takes note of Player as he waits for Ephemer in the Fountain Square, taking a keen interest in them. After witnessing Player's battle with Aced, Strelitzia is approached by Ava and asked to be one of the new Union leaders following the events of the Keyblade War. Concerned about those who will be left behind during the Keyblade War, Strelitzia remembers that Player is not a Dandelion, and insists that she has to warn Player of the danger that is to come. The next day, while searching for Player in an abandoned house, the two of them are attacked by an unseen assailant, who steals Strelitzia's rule book before leaving. Streltzia holds her Chirithy in her arms, sad that she did not get the chance to see Player, before both she and her Chirithy fade away.
Ephemer, Skuld, Ventus, and Brain grow concerned when the fifth Union leader does not show up and begin searching the Keyblade Graveyard. Soon, Lauriam approaches, apologizing for being so late, as he had been searching for something.
Together at last, the five enter the Foreteller's Chamber in Daybreak Town, where Brain looks through a copy of the Book of Prophecies that he finds. Ultimately, they decide to keep the Unions united under a Union Cross for the time being, while also keeping the absence of the Foretellers a secret. Brain then decides that in order to celebrate, they should make creating new Spirits their first task, sending Ephemer, Skuld, and Ventus to collect the supplies while he and Lauriam prepare to synthesize the materials.
