4-The 13 Crystal Skulls
It is said that there are 13 crystal skulls scattered throughout the world and that on the day when mankind finds all the skulls and can gather them, something extraordinary will happen. For many years, supernatural powers have been lent to these antiquities, including the fact that they could cure diseases. Several legends have been built around them. First of all, F. Gendron, who held a skull in the nineteenth century, explained that if all the skulls assembles, the Aztec empire would be reborn from its ashes.
