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