Archaeological evidence on Orban, including a pyramid, mosaics, and a figure of Chalchiutlicue, the Aztec goddess of water, suggests connections to Teotihuacan, a city in pre-Columbian South America which flourished for centuries as a religious and economic mecca before suffering a great upheaval in 750 AD, possibly brought about by the Goa'uld. The reason for the disappearance of the Goa'uld from Orban within the last few hundred years is unknown, however the culture evolved rapidly after the Goa'uld abandoned the planet. Now an impressive society with modern cities, the Orbanians have accomplished in a few decades what it took humans on Earth nearly a century to achieve.
