Esther
Stardust Pillar
Fairylands takes place after GWWDYM?
so even if the others can't leave (yet), Esther (and Vir as well likely, without either being aware that the other got sent as well) would be sent to Fairylands, insert entire FL plot happening except with Vir also adventuring on her own trying to find a way to Alghan finally, Esther ends up back in Floralis while Vir ends up in Streamia somehow, Esther realizes she still hasn't found her main team, goes back to Streamia, cue the BH storyline continuing
No it doesn'tat leat your lore has some sanity in it
