The Mission Behind This Book

Twenty percent of net royalties from this book are donated to Troy Brewer Ministries — rescue operations for trafficked children worldwide.

The Watchers defiled what God made. The work of rescuing the defiled is not finished.

This is not a gesture. It is a line in the sand.

As the world prepares to ask what these beings are — Scripture has already answered.

Why do over 500 cultures preserve flood legends?

Why do giant traditions appear on every continent?

Why did ancient humanity build structures reaching toward heaven?

They remember. Not perfectly — but genuinely.

Every culture that built towers, told flood myths, and remembered giants in their founding legends is preserving a structural pattern of real events. The details vary. The shape doesn't. These aren't coincidences — they're echoes.

The Hidden Portals trilogy traces this pattern from Genesis to Revelation — through Second Temple literature, ancient Near Eastern archaeology, and the global oral tradition — arriving at a single theological conclusion that explains all of it. This series occupies the ground no one else is standing on.

The Central Argument

Portal theology traces a single thread through all of Scripture — from Eden's guarded gate to "I am the door." Five theses. One unbroken story.

Five Core Theses

I

The antediluvian world possessed regulated heaven-earth portals where divine and human realms intersected under God's authority.

II

The Watchers breached these portals at Mount Hermon, initiating unauthorized crossing that corrupted both realms.

III

The Flood served as divine seal, closing the unauthorized portals and resetting the boundaries between realms.

IV

Post-Flood humanity repeatedly attempted to reopen these sealed portals through ziggurats, pyramids, and sacred mountains.

V

Christ alone provides authorized portal access — "I am the door" — fulfilling what every ancient attempt counterfeited.

From the Book

"The fairy tales remember. Not perfectly — how could they after millennia of oral transmission, cultural adaptation, and deliberate suppression? But they remember. The giants lived in the sky. They hoarded treasures. They ate humans. And brave heroes climbed impossible heights to defeat them."
— Chapter 1: The Beanstalk as Fossil
"Mount Hermon's very name whispers its secret. In Hebrew, cherem means 'devoted to destruction' — the same word used for objects so defiled by association with false gods that they must be utterly destroyed. The mountain where the Watchers descended bears a name that is itself a warning."
— Chapter 12: Mount Hermon
"Adam was not a gardener. He was the first priest. Eden was not a nature reserve. It was the original sanctuary — the cosmic temple where heaven and earth met under God's authorized terms."
— Chapter 5: Garden Temple

About the Author

M. Dustin Brimberry

At the Cyclopean walls of Mycenae

M. Dustin Brimberry

M. Dustin Brimberry is a researcher, writer, and teacher whose work sits at the intersection of biblical theology, ancient Near Eastern literature, and the question every serious student of Genesis eventually asks: what was the world like before the Flood?

Drawing on Second Temple sources, Mesopotamian archaeology, and global oral tradition, Brimberry builds a case that the pre-Flood world was not a blank slate — it was a world of open portals, deliberate transgressions, and a divine response that sealed the access humanity had abused. The Hidden Portals trilogy is the full account of that story and its redemption in Christ.
