It is not commonly known, but an advanced civilization inhabited this area more than a thousand years ago. They were known as the Rojeri-Sa, and little evidence remains of their greatness. Their power was so vast, the area still bears their name a thousand years after their disappearance: Rogers.
What we know of these people comes mostly from stories passed down by native people, and from descriptions of Rojeri-Sa buildings discovered in the forest by early European explorers. We do know that at their peak they were far more advanced than any other civilization on Earth. They understood the concepts of Longitude and Latitude as we know them today! It is the sincere belief of a very small community of archaeologists and anthropologists -- myself among them -- that the reason for their advanced technology was their association with extraterrestrials.
Please do not think I am mad! We have suffered greatly for these beliefs, and are treated with derision by our colleagues. But we have proof! We have collected stories that tell us the Rojeri-Sa had sophisticated electronic devices -- not dissimilar to our own -- a thousand years or more before our civilization developed the first semiconductors. Indeed I have in my possession bits of technology found in the area that are strikingly similar to what we enjoy today, but it is obvious that they are ancient!
The Rogers Codex was found in 1807 in the remains of a Rojeri-Sa temple complex, in a vault located at the posted coordinates. There is no point going there today because all traces that ancient place have been obliterated. It is now private property, and the owners have tired of scientists and treasure-seekers wandering their land. Stay away!
One page of the Codex has defied interpretation. We believe it describes the location of a treasure of tremendous value. Please help us decipher it. A culture that lived with extraterrestrials wants to communicate with us!
