For centuries, legends have whispered of an extraordinary group of ancient people whose lifespans stretched two or three times longer than ordinary people. Though not truly immortal, these enigmatic individuals amassed lifetimes of unparalleled knowledge, their advancements so astonishing that they were mistaken as gods.

They shaped humanity's most extraordinary achievements: the Great Pyramid of Giza, the Ming dynasty's Treasure Ships, the lost city of Atlantis, the Pyramid of the Sun in Teotihuacán, and a global communication network – known as the Looking Glass – that linked the world four thousand years before Columbus crossed the Atlantic, earning them the title of Master Builders.

When the last of the great ones died, their vast knowledge of the ancient world was buried with them in a secret tomb some believed was never meant to be found. If such a necropolis existed, it would be much larger than even the Great Pyramid of Khufu, its treasures eclipsing those of King Tutankhamun, and guarded by an ancient army more formidable than the Terracotta Warriors who protected the Mausoleum of the First Qin Emperor.
