The World Wreckers

The mysterious Andrea Closson accepts a contract to wreck the economy of Darkover, so that the planet must turn to the Terran Empire for assistance. Closson's thoughts reveal that she is a native of Darkover, a child of the Yellow Forest.

Regis Hastur survives another assassination attempt. He and his paxman, Danilo Syrtis, discuss the many mysterious deaths besieging the Comyn. Regis recalls that his two sons are among the deceased, and that many of the old Comyn families have died out altogether. He asks the Terrans to seek out telepaths on other worlds and send them to Darkover, for what becomes known as Project Telepath.

At Arillinn, Regis meets Linnea Storn, a matrix technician. He learns that her grandmother was Desideria Leynier-Storn, the leronis who raised Sharra to restore High Windward to its rightful family (see The Winds of Darkover).

Citizens from all over Darkover apply to Regis for assistance, describing economic problems, crop failures, and fires. A member of the ancient Darkovan chieri race arrives and asks to speak to Regis. He volunteers to assist in Project Telepath.

The members of Project Telepath meet and evaluate each other. A number of tests are run. Missy proves to be a troublemaker. They discover that Keral is a hermaphrodite. Further tests prove that Missy, whom they originally believed to be human, is also a chieri. As events unfold, it will become clear that chieri can be either sex, and can change gender at will.

Two free Amazon guides arrive at Arillinn and ask to see the Keeper, Linnea Storn. They describe a recent client, Andrea Closson, whom they guided through the back country. They suspect that she has something to do with the ecological disaster that seems to have befallen Darkover. Linnea contacts Regis with this information.

Regis calls for all of the telepaths on Darkover to join him to combat the threat. During a festival dance, their minds join in ecstasy and call into the castle the form of Andrea Closson, whom one of the chieri identifies as a lost member of his people. Accepted back to her own people, Closson uses her own fortune to restore Darkover's ecology. She is able to find hope in her people's survival in Keral's child with Project Telepath member David Hamilton, a union such as resulted in the strain of the Comyn.

Regis creates a Telepathic Council dedicated to working in limited cooperation with the Terran Empire.[2]
