In the games
Near the end of the Delta Episode, Zinnia reveals to the player that she and Aster used to be together all the time before the latter was lost.
According to an interview with Shigeru Ohmori in the June 2015 issue of Nintendo Dream, Aster was a person with special powers who held the position of Lorekeeper before Zinnia, much like Aster in Pokémon Adventures.

Aster debuts in the Omega Ruby & Alpha Sapphire chapter. She was one of the Draconids and was given the title of Lorekeeper due to possessing special powers. She had also befriended Rayquaza, the Legendary Pokémon revered by the Draconids, and was the only known member of the clan to have permission to ride on top of it.
When the Devon Corporation came to the Embedded Tower in hopes of capturing Rayquaza so that the Pokémon Association could study it, Aster fought alongside Rayquaza in order to stop them. Though the battle went unseen, Rayquaza was successfully captured and taken away along with several Key Stones that Aster had collected. When Zinnia arrived at the tower, she found the area in flames and that Aster had died during the battle. Traumatized by Aster's death, Zinnia began to cry so much that her voice eventually gave out. She also took a partially burnt cloak belonging to Aster as a memento.
With Aster dead, the title of Lorekeeper was passed down to Zinnia. Despite this, some Draconids were opposed to Zinnia becoming the next Lorekeeper, as she was not as strong as Aster and did not possess the abilities needed to stop the meteoroid that was foreseen to crash into the planet.
| Noivern is Aster's only known Pokémon. It was first seen helping Zinnia battle against Ruby and Sapphire in order to convince Rayquaza to join Zinnia's side. Sensing the lingering presence of Aster on top of Noivern, Rayquaza was attracted towards Noivern, who led it away from Ruby and Sapphire so that Zinnia could talk to Rayquaza alone.
Noivern's only known move is Boomburst.
