Evalla
From The Stargate Omnipedia
Wife of Pallan, Evalla was a thoughtful and intuitive individual from planet P3X-289. She led Daniel Jackson to the storage repository where all the ancient texts of her people were kept prior to the introduction of the Link, as well as aiding him in researching the texts.
When the Link was forced to reevaluate its population growth to compensate for the decreasing integrity of the bio-dome, it chose to execute Evalla by having her exit into the hazardous waste of the outside environment, killing her.
