Cuttlefish That Loves Diving
Aurore might be an apprentice perhaps? The flying and sparkles could be one of those parlor tricks low rank apprentices can perform and the star gazing a foreshadowing of future traveler tendencies? just a wild guess though.. .. maybe she just got corrupted by the cosmos too. losing her to madness would free the MC to travel and learn more about this world (and grow).... so her death might be necessary praise the sun! ☀️🙏
Lumian already working on Provoker without even starting the pathway :p. Aurora is interesting... someone speculated she might be a transmigrator, and I would adore if that turned out to be the case. All the French being used reminds me of when I read Poirot books and hunted down meanings. At least that taught me some stuff so it's easier coming across the words now.
It is almost certain that these terms of endearment from a few hundred years ago were plagiarized by one senior in particular, I also suspect that before he came the people of the Republic weren’t quite this… French. Pointless musings and nonsense speculations start here. The sister very much sounds like they are in the Door pathway to me but there are others that could fit. At sequence three they would have the ability to traverse the cosmos and visit other planets and civilizations, the brother could even be a souvenir from such a trip though those guesses are probably a bit of a reach. The things the sister says are definitely red flags regardless of her actual pathway and sequence. If she is a sequence three of the door pathway under the influence of the outer deities she would make excellent advancement material for Fors, give us a high level beyonder battle with the Tarot Club capturing and killing this spy for the evil outsiders and setting the young man on a misguided path of revenge for his sister!!! Jokes aside there is too little information to really work with so far and all I can currently offer are the more far fetched nonsense my mind can produce.
