The Lost book of King Og

This modern work by S M Demon claims to be taken from ancient preflood heretical texts withheld by the vatican. It is known as the last written words of the Rephaim. It tells a story of the Giants civil war between OG the Rephaim king of Bashan and Nimrod the Nephilim king and their armies over the accidental murder of a moon child that was the Giants hope to continue their race. This is a fascinating book that of course Wikipedia will tell you is fiction, but it feels pretty close to reality to me, but you be the judge and make of it what you will.
