From The Stargate Omnipedia
Originally controlled by the System Lord Morrigan
, the planet was under Goa'uld
oppression until, for unknown reasons, it ceased to be (possibly an uprising as the Stargate
was buried). The people were allowed to develop and progress in their own direction. Eventually the inhabitants dug up the remains of what they referred to as the Gate of Mahg Mar
, located within the Ruins of Danaan
(possibly a central place of worship for Morrigan). The gate was put on display in the planet's Museum of National History.
The culture became technologically advanced and furthered in their studies of science until a cataclysmic event made the entire world uninhabitable. The people quickly devised a solution to save a handful of lives: an artificial containment dome, pristine in it's simplicity above-ground, but regulated by an advanced piece of machinery below. Once inside, their world crumbled beyond the barrier, but their technology continued to advance until they developed a vast super-computer known as The Link, capable of integrating the entire population into one enormous database.
The people signed a contractual agreement before connecting to the program and submitted themselves to its care. Over time, the bio-domes's power source began to fail. The Link had no choice but to sacrifice individual citizens to maintain the population of the whole and the suitable integrity over the course of 200 years.
After the dome had existed for some 400 years, SG-1 arrived, impressed by the structure and the sophisticated technology within it. It didn't take them long to realize that the dome was failing and the Link was rewriting the people's memories to prevent them from realizing the horrible atrocities taking place by a computer programmed to protect them.
SG-1 managed to save the people from the control of the Link, and relocated them to another planet. P3X-289 was abandoned, its entire environment poisoned and the dome doomed to fail in a matter of weeks or months.
