It will be a challenge dividing the work into 2 when Adastra was simply the only 1. Interea seems to fill in ALOT of plot gaps within Adastra; essentially making it Adastra 1.5 which is seriously too much work. If it were me, I would focus primarily on Khemia if it means propelling us to Adastra 2 whatever the pacing may be. Interea? Allow the audience to create their fanfictions of events.
