Wait what? So, looking back at the first chapter, at least 10 generations of royalty have gone by since the "prophecy" about the birth of "the third star" - that is to say, minimum of 200~ years - but somehow MCs friends from her time as an archmage are looking for her? Was there no time lapse at all between her "death" and "reincarnation"? When she was alive as an archmage was she aware of some random distant kingdom with a weird prophecy about a "third star"?
I don't get how the timeline lines up is what I'm saying.
