Dandelions

The Dandelions (ダンデライオン) are a group of exceptional Keyblade wielders from each Union who possess a certain aversion to darkness.

Kingdom Hearts χ
As per her role, Ava assembled the Dandelions and trained them in a secret location to prepare them for the travel to the world outside when the Keyblade War broke out so that they could ensure the survival of light.

Five individuals were chosen by the Master of Masters to succeed the Foretellers after the Keyblade War; though only one of them would receive a copy of the Book of Prophecies, and they would be the only ones permitted to remember the world the Dandelions left behind. Ephemer was the first to be approached by Ava when his curiosity lead him to seek answers about the world. Ephemer then reached out to Skuld so that she would follow the same path as him and join the Dandelions, with Skuld destined to become one of the new Union leaders. Strelitzia was the final Dandelion to be approached by Ava, but in trying to convince Player to join the Dandelions, she was eliminated by an unknown individual, who then stole her rulebook and took her place as Union leader. Brain, Ventus, and Lauriam would later gather in the Keyblade Graveyard as the new Union leaders, though it is unclear which of them is the impostor.

With a Union χ instituted, the Dandelions would be allowed to work with one another, regardless which Union they were loyal to, to continue maintaining the balance by collecting Lux.
