In 1992, the Smithsonian Museum in Washington D.C. acquired a mysterious artifact with unclear origins known as the Crystal Skull. It was the size of an average human skull, made of milky white quartz, but more importantly, it was said to hold supernatural powers and ancient wisdom. And it wasn’t the only one… Those who’ve come into contact with the skulls have had prophetic visions, disturbing dreams and have even encountered deadly curses – but to this day, no one knows who made the skulls, or why.
