The First Incan Key

The First Incan Key was discovered in Bolivia by Nigel Cooke. It is a stone key about the size of a chess piece. Inscribed upon it is a clue that leads to the Second Incan Key. The clue is as follows:"'In the seat of the Andes Mountains, by the Rio Olvidado, lie the bones of the underworld that guard the key to silver and gold.'"This can be interpreted as follows:

The seat of the Andes Mountains refers to the Andes Mountain range. The reference to the Rio Olvidado (a river) is hinting at the town Olvidados (which is near the Rio Olvidado). The bones of the underworld are the bones within the crypt of one of Olvidado's local churches, The Cathedral of the Lost Souls. The key to silver and gold is referencing The Second Incan Key.
