"Warn him? In what fashion may Helmor be warned in time--even were he minded to give ear to any word out of Tamarizia? Jason, you speak in riddles." Croft nodded. "Nay--Helmor would pay little heed to Tamarizian words, but were he to dream--" "Dream--" All at once Gaya caught her breath. Her glance met Croft's in a subtle understanding. "Jason, thou meanest--thou canst induce a dream in his brain?" "Aye." For the second time Croft nodded, well pleased at her intuitive understanding. "Why not? Gaya knows how in the spirit I called Naia of Aphur's spirit to me, before our marriage, and that nightly now we speak so together concerning our love and this present thing; also that I speak so to Zud of Zitra when the need arises, having taught him to answer the call of my spirit. Wherefore, may I not visit Helmor in the spiritual presence and by the same force inspire a vision of his and Zollaria's danger in his mind?" For that was the thought that had come to him on waking after his return from Berla--the conception of the manner in which Helmor might be warned and fresh caution inspired in his guarding of Naia of Aphur and Jason, son of Jason, and even Helmor's self against the perils involved in Kalamita's schemes. "By Zitu!" Robur mumbled again. But Gaya sat brooding the thought for a moment longer, presently lifting her head to murmur, "Three times. Let the dream be repeated once and yet again, Jason, until it takes possession of him wholly, nor is absent from his thoughts at any time." * * * * * Croft started slightly. He had only considered the one inspired dream of warning, but now, he realized swiftly the value of Gaya's words--the weight attached to the repetition of a dream. Her suggestion demanded acceptance. "Aye, Gaya," he assented. "Ga speaks through you to the benefit of child and mother. The dream shall be repeated three times, on as many nights--until Helmor is convinced of an agency behind it, even though the nature of that agency he fails to suspect." Robur rose. His manner was restless. Suddenly he whirled around. "You can do this thing?" he questioned. "Is naught forbidden to you, my friend? You can enter the mind of another and order the shape of the pictures in his brain?" Jason eyed him for a moment before he answered. "Naught is forbidden to the seeker after knowledge, Rob, so he see not from evil purpose or for merely selfish gain. All life is a rhythm--even as the sound of the harp given off from a vibrating string. And if I alter the rhythm of Helmor's mind to the preserving of the life of my child, the honor of his mother, the estate of himself, and the lives of his people, were the action vain?" "Nay, it were a work of justice and mercy," exclaimed Gaya before Robur found words in which to respond. Croft lifted a tiny vial and held it toward both man and woman. "Behold!" he cried sharply. "Fix your eyes upon it."
