If anyone wants the REAL scoup on Nephilim, I suggest reading Zacheria Stichen's books. The Nephilim have visited this planet every 3,600 years, and is due to return sometime this decade. Their world, not unlike our own, is called "NIBIRU", or "The 12th Planet" Ancient texts going back 6,000 + years have been translated and speak of the Nephilim visiting Earth. Archeological digs find strange layers within the ground every so often, measured and dated at roughly 3,600 year cycles. This seems to confirm the ancient texts talking about Nibiru returning, disrupting gravitational fields within our solar system. It has been confirmed and verified that this 3,600 year cycle has been responsible for many disasters here on Earth, as well as documented in the ancinet texts, have caused disasters on other planets in our solar system.
There is more to the Nephilim than depicted in the Prophecy game. And it isnt science fiction either.
Stichens books are available at any bookstore and online. I highly recommend reading them. Although many aspects of the Nephilim are correct in the WCP game, there are also some that are not exactly true, or even come close to being correct.
