The Hollow Earth theory is a rather popular topic ever since it was proposed by Edmond Halley in the 17th century and popularized by authors like Edgar Rice Burroughs, Jules Verne, Giacomo Casanova, Ludvig Holberg, and even Edgar Allan Poe; the theory that, deep beneath the feet we walk upon, there is a subterranean world where creatures and civilizations live and thrive miles below the surface under our feet. Of course, such thoughts were regarded as flights of fancy and thought to be put to rest by Pierre Bougouer and Charles Hutton in the 1740's and 1770's respectively. However, following the rise of the Kaiju starting with Godzilla in 1954, perhaps Edmond Halley's theories held water after all.

It could explain how Godzilla and the other non-flying Kaiju were able to disappear off the radar only to reappear without triggering early warning systems. They could have been using Hollow Earth tunnels akin to wormholes. With the Kaiju currently in hibernation ever since their last appearance in 2945, a GRID scientific unit headed by Dr. Asuka Serizawa, the last living relative of the late Dr. Daisuke Serizawa, discovered Halley's theory was correct as several tunnel networks were discovered near the bottom of the Marianas Trench. However, drone footage has also revealed something connected to the Hollow Earth theory; hieroglyphics depicting humans seemingly worshiping the Kaiju as gods. Not just worshiping, but living along side them, even fighting along side them. Godzilla himself even seems to stand along side the ancient humans. In a time when humans waged war with the Kaiju ever since the King of the Monsters first revealed himself on Odo Island before ravaging Tokyo in early November, it is shocking and uncomprehending to believe humans and Kaiju, let alone Godzilla, lived side-by-side. Now the real questions rise up: What broke that coexistence and is it possible to mend that harmony again?

As the fear of the Kaiju coming out of their dormancy as well as more and more Kaiju being discovered in hibernation all over the world and the threat of a war between men and monsters being all but inevitable, it is detrimental the generations of today find the key to restore harmony before it's too late... and time is quickly running out.
