Prior to the Keyblade War, Strelitzia, a member of the Dandelions selected to be one of the new Union leaders once the war ends, attempts to convince Player to join the Dandelions, but she was eliminated by an unknown individual, who then steals her rulebook and takes her place as Union leader.
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, 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, Skuld, Ventus, Brain, and Lauriam gather at the Keyblade Graveyard to meet with their fellow Union leaders, with Lauriam being the last to arrive. Together, the five enter the Foretellers' 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 χ to prevent future conflicts between Keyblade wielders. Brain 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.
Meanwhile, Player resumes their missions, initially reliving through the events leading up to the Keyblade War, and later making use of the newly created Union χ, joining a party of fellow Dandelions and traveling to new worlds. Soon, Player begins having nightmares of the Keyblade War. Chirithy, concerned of the frequency of Player's nightmares, reports this to Ephemer and Skuld, who encourages Chirithy to protect Player from the truth. Afterwards, Ephemer and Skuld begin to investigate a new impending darkness in the world.
