An imposter worked for C19 in the 1970s. She impersonated Jana Kristan after she had been assassinated. Her orders from the Pale Man were to find the Silurian shelter and bring one to him.
After gaining Liz Shaw's confidence, she and Liz went to the island of L'Ithe. After shooting a Silurian that had come to greet them, the imposter revealed herself to Liz and took her underground to the Silurian shelter. They soon entered the council chamber, where the imposter shot and killed the shelter leader Chukk, wounded Krugga and shot Liz in the shoulder. The Silurians in the chamber then killed the imposter with their third eyes. (PROSE: The Scales of Injustice)
