The creator of this book appeared to be a miserable person based on Aur's understanding from the introductory part.
The person possessed exceptional talent but became obsessed with a variance spell.
In pursuit of this spell, he collected various materials for research and completion, intending to create a terrifying spell.
Unfortunately, the research took too long, and the man's mortal body perished before he could create the vital spell.
Although Aur wasn't sure about the nature of the spell the man was researching, which led him to sacrifice his entire future, it piqued Aur's interest.
However, it was all in vain, as the man had already met a tragic end with the mercilessness of time that no one could escape from.
Aur sighed thinking of this as he carefully turned the pages until he found the one marked with a feather.
