King Kong of Skull Island

Part 2: The Wall reveals the astonishing history of Skull Island after the arrival of the first human civilization, the Tagatu, accompanied by the prehistoric Kongs. Their penultimate war for species survival versus the island's forward-evolved denizens and their super-saurian queen, Gaw, explodes against the backdrop of the building of the iconic Wall that still spans island's peninsula.
Millennia before the Golden Ages of Egypt and Greece, a uniquely marvelous race of humans existed on the shores of what today is a portion of the northern rim of the Indian Ocean, on the northeast side of the Andaman Sea.
They called themselves the Tagatu. They could have-perhaps would have-ruled the world.
And then they vanished.
Their former greatness and their relationship to the giant species of anthropoids known as the Kongs are only hinted at in a colossal Wall that still spans the peninsula of Skull Island. How did the Tagatu come to live on that prehistoric island, and how could they have built such a Wall in the midst of so many terrifyingly powerful dinosaurs?
Note: King Kong of Skull Island - Part 1: Exodus and King Kong of Skull Island - Part 2: The Wall combine (with much additional narrative and extra illustrations) to make up the crowd-funded Limited Edition book 'King Kong of Skull Island' that was not available to the public except for those that backed the campaign.
