>>57337451>Zinnia’s too young to have kids, from what we know. Canon (per Ohmori interview and Adventures) is that Asteroid was the previous lorekeeper.Zinnia is a young woman (20s) teenage pregnancy is possible, Aster being the previous Lorekeeper doesn't negate that she could be her daughter (if she was the "chosen one" of the clan the logical thing is that they train her as Lorekeeper since she was a child, skipping Zinnia as a successor)
in the teraleak it is mentioned that Aster is Zinnia's daughter and in the magazine in which Ohmori is interviewed I remember there is a section that says that Aster being Zinnia's daughter is a possibility
Ohmori also says that the relationship between Zinnia and Aster was left "vague" on purpose so that the player would "use their imagination" (why?)
It's not like GF is going to delve into Zinnia's past or even use her again in another game anyway.
