The grimoire looked very dark and it gave off so much dark energy, he never saw a book like this during his life in district one, people cast their own spells without any need of a grimoire.
'Maybe it is because they are all weak, and their spells don't consume a lot of their divine energy' Isiah thought as he was trying to open the grimoire.
'Whatever is in there, it is certainly very dark'
He tried not to think that much and applied the necessary force to open it, yet it didn't open. He increased his force but it was the same result.
Despite all of his physical strength he couldn't open it, he even thought at a moment that maybe he was doing it wrong .
' Maybe there is another way' He thought again after failing a lot of times.
He started to look at it this time very carefully, it was shining in the middle of the darkness which confused Isiah so much .
