Stephen Leeds, AKA “Legion,” is the series’ hero, a man whose unique mental condition allows him to generate a multitude of personae: hallucinatory entities with a wide variety of personal characteristics and a vast array of highly specialized skills.

The third entry in the series, Lies of the Beholder, begins with two seemingly unrelated events: the disappearance of Armando, one of Stephen’s many “aspects,” and an unexpected cry for help from Sandra, the woman who, many years before, helped him learn to live with his condition. These events lead Stephen, along with several of his aspects, to a sinister high-tech firm specializing in advanced methods of human incarceration.
