Paris, 1804. The German scientist Alexander von Humboldt returns from a five-year expedition, considered as the second great discovery of America. While publishing numerous significant scientific papers about the American continent's culture and nature, he neglects to publish detailed studies on the Pyramid of the Sun, despite spending considerable time in Teotihuacan, one of pre-Columbian America's oldest and largest cities. Only shortly before his death, Humboldt manages to recreate an ancient pyramid-shaped artifact which reportedly was used to select those worthy of access to the Pyramid of the Sun. The parts of this artifact were recently found in the archives of Humboldt University of Berlin.
