It is the Jaffas' homeworld. The land is filled with big forests and alluvial hillsides. The planet orbits a binary star system.

The main city, also called Chulak, seems to be linked with the Roman civilization, judging by its architecture.

This planet was previously used by the Goa'uld Apophis to choose human hosts. The ceremony of implantation, called "Prin'ta", was very common. But, because of SG-1, the planet is now free.
