Nirrti

Nirrti was a Goa'uld System Lord who experimented to discover advanced humans.

Biography
Nirrti seemed obsessed with creating enhanced humans (hok'taur) which could serve as hosts. She tried various experiments including one which ended up with the only survivor being a young girl named Cassandra. Cassandra lived and was adopted by Dr. Janet Fraiser.

Later, Nirrti was one of the System Lords sent to negotiate with the Asgard to include Earth in the Protected Planets Treaty. She felt that the Tau'ri were too much of a threat, and also coveted Cronus' territory. Using phase shifting technology, Nirrti attacked Cronus in his quarters, framing Teal'c for the attack. Jack O'Neill decided to bluff, saying that they new she was experimenting with phase shifting technology, and she became a prisoner of Cronus.



After Cronus was killed by SG-1, Nirrti found out that Cassandra was still was alive and attemted to find more information about Cassandra to be able to conduct more experiments on other people. At one point, she manages to sneak into the SGC using a cloaking technology that makes her invisible. She was eventually discovered. Captured, she offered to help save Cassandra, who was dying of a retrovirus that was turning her into a hok'taur, demanding her freedom, cloaking device, and a sample of Cassandra's blood. General Hammond initially refused. In an act of desperation, Dr. Fraiser held Nirrti at gun point, demanding that she help. After Hammond agreed to free her, and reminded her that Fraiser was Cassandra's adopted mother, Nirrti healed the girl, and was allowed to leave unharmed.

The Russian SG-4 team later discovered her experiments to create a hok'taur on the planet P3X-367, this time through genetic maniupalation, finding Alebran in his ruined city after he had left Nirrti. They brought him back to the SGC to speak to SG-1, as it was because of them that Nirrti was still free. Alebran informed them of all that he knew but soon died due to Nirrti's experiments, seeming to turn into liquid. The two SG teams returned to the planet in order to help the natives, but the natives did not believe that Nirrti was evil as she had been the one to save them from a plague which had ravished their planet. Teal'c and Jonas Quinn were taken prisoner by the natives after Eggar discovered their intent to kill Nirrti in O'Neil's mind, and the others were soon captured upon Nirrti's return also.

SG-1 attempted to inform the native's of Nirrti's true motives while Nirrti performed experiments on both teams, meeting with no success for some time. Nirrti performed several experiments on members of both teams before finding that Jonas's Kelownan heritage had caused him to be somewhat more evolved than the Tau'ri. She was sure she could create her hauk'tar in him, and even asked if he would submit to allow her to do so. Although Jonas rejected the offer, Nirrti none-the-less performed several experiments on him. During this time, however, SG-1 was able to somewhat convince the natives of Nirrti's true intents and after Eggar read her mind he discovered this to be true. He and Wodan then killed Nirrti, but not before she could give Jonas the ability to see into multiple futures.
