Finally, the secret Valley of the Jaguar! That's good news! But, this time I have two pieces of good news. The main computer back in the spaceship is still active and I was able to connect with it! I found the sacred item we are looking for.
It is a crystal skull, made of a crystal that Mayans found in crater where a meteorite hit, around 300 A.D. This crystal is some kind of Sirian material used for constructing starships. There are reports, in the computer, of a Sirian Scout ship lost over the hills of Sierra de Chiapas during this time.
The crystal skull should be here somewhere, probably in the highest chamber of the biggest temple on the furthest side of this valley. I mean, in other words, it should be the one in the middle.
I can see the ceremonial plateau in the middle. I guess we should check it out.
