Second Foundation
Pelleas Anthor was originally introduced as a researcher in electroencephalographic analysis. Together with Toran Darell II, Jole Turbor, Dr. Elvett Semic and Homir Munn, he sets about using information obtained from brain scans to find the Second Foundation, and to eventually destroy it. However, it turns out that he is in fact a Second Foundation agent who had infiltrated the group to monitor, and if possible control, the direction of the dangerous actions being taken. In a twist within a twist, he was actually part of a Second Foundation deception led by Preem Palver.
