The climate of the planet is tropical and has plenty of trees and water. There is a city in ruins on the planet by an advanced civilization.
Long ago, brought Omeyocans a group of people to the planet via Crystal skull. The residents developed their own civilization in peace and became an advanced culture. They used the Crystal skull to travel to Earth and do commerce. One day an army of Aztecs came to the planet via Crystal skull and took control of it as Yaxkin people could not escape or contact other worlds to help. But then Coatlicue in her spaceship and brought with her a Stargate. The people did not know about warfare or how they fought, but they knew about the advanced biotechnology, weapons. They did not know anything about Stargate.
Yaxkin unleashed a bioweapon that killed the enemy except Coatlicue and later mutated and killed locals. Those elders of the people left a message in written in a building about the incident and that the virus died out with them the last of the people. A long time later arrived SG-1 and Nicholas Ballard to the planet to investigate it and found it deserted and the city in ruins, but no sign of a struggle. After they learned of the incident. They then helped over 250,000 of Xalótcan evacuate to the planet via Crystal skull after their own homeworld was destroyed. (SG1: "City of the Gods")
