Aurora's dark witchcraft notebooks were lying quietly at the bottom of the box.

On the way to Trier, Lumian had roughly checked them, and found nothing suspicious. After all, Aurora is not a person who likes to write a diary and record moods and various trivial matters. Her witchcraft notes are really just notes, full of various mystical knowledge, and copied many spells, symbolic patterns, and material selection principles.

It may be that Aurora likes to keep accounts. Most of these spells are marked with when and where how much money or what things were exchanged.
