Eventually the Galactic Patrol decides that having only one “Vortex Blaster” is inviting disaster. If something happens to Storm Cloud, they are at the mercy of the loose vortices again. As a result, Dr. Cloud is called back to Tellus (what the Earth is called in Smith's stories) and given a new ship. A specially modified, light cruiser (called Vortex Blaster II ) outfitted to carry everything that is needed to extinguish vortices. He is also introduced to Joan Janowick, the leading computer expert of Civilization. Her job is to build a computer that can reproduce whatever it was that Storm Cloud does and blow out vortices like he can. Working closely with Joan on a series of ever faster computers, his eyes soon turn more and more toward his pretty, super smart, and self-taught psychic co-worker and his heart begins to heal. As they fall in love, he bonds psionically with Joan, a pivotal point in the novel, as this leads him to find and communicate with the pure-energy alien beings
