Keral and David Hamilton form a tight bond of friendship and love and learn to overcome shyness and differences to become a couple. They learn to love despite differences and have a child.
Keral is from the Yellow Forest and was sent by his people to join the Darkovans and Terrans in their Project Telepath. Keral believes he was sent due to the fact he was the youngest and was more able to adapt to being among humans.
