Two of the notebooks were apparently school notebooks; one from high school and another from an earlier grade, with information quickly jotted down. All three of the books were filled with doodles, scribbles, and incomplete stories. There were many pages where only a few sentences were written, or stopped mid-sentence and never completed, reflecting a disorganized mind.
While some of the stories seemed lighthearted, the most complete were rather dark. One of which was about a cat trying to find his friends in a winter wasteland and desperately fighting off a giant grotesque beast, but ending up beat up and apparently left to freeze to death.
Another story seemed somewhat recent, about a curious guy forcing his friend and girlfriend to join him on an attempt to explore and document a dangerous territory against their wishes, which results in their deaths. The guy survives, writhing in guilt, and... well, it was left unfinished, but it hinted at what was to happen next.
