That Time I Entered an Occult Bookstore and Ended Up With Magical Powers!

A young woman by the name of Iyla happens upon a magical codex that accidentally becomes registered to her, marking her as a new magus, and giving her the Sight, an ability to see the unseen and hidden parts of her world that is normally undisclosed to outsiders without a need to know. Bewildered by her new powers, she learns to use them and interacts with creatures and peoples straight out of her favorite stories!
