Through these experiences, the traveler grapples with their inability to control the minds they enter, ultimately finding themselves trapped in the psyche of a mentally ill man named Mersey. As Mersey articulates the dire state of his original civilization, the alien realizes that their race's survival might come at a cost that compromises their identity.
