Those who read "Palos of the Dog Star Pack" and "The Mouthpiece of Zitu" will remember that Dr. Jason Croft, having, during his psychic investigations, gained complete control over his astral form, lands while wandering among the planets of outer space upon Palos, one of the spheres of the universe which includes the Dog Star. There he sees and falls in love with Naia, Princess of Tamarizia and, seizing upon the body of a Palosian about to die, he enters into it and in this form, with his advanced knowledge soon makes himself a power on the planet. Several times he returns to his own body on earth; but finally, having won the love of Naia, married her and made himself practical dictator of the planet, he allows his earth body to die and goes to Palos for good. This is the status of things when in the present story, he again gets into communication with his friend Dr. Murray. Of the present story we will only say: "You know that the first one was good and the second better; the third is undoubtedly the best of the trilogy."
