Enoch - And I saw at that time how a like abyss was opened in the midst of the earth, full of fire, and they brought those blinded sheep, and they were all judged and found guilty and cast into this fiery abyss, and they burned; now this abyss was to the right of that house.

Notes

The book of Enoch is not part of the canonical scriptures (The Bible) we know today and we don't know how accurate it is.

Some belive while Enoch is not inspired by God that it still serves as a historical book on the time before the flood. It's also quoted in the New Testament in Jude 1:14-15.

Because of this I wanted to include this book for historical reasons.

I would recommend reading the Bible first and foremost as it should be your foundation. Then if you are intrested you can take a look at the book of Enoch.
