He thought that there ought to be a way to compensate for this too, to protect a developing child. But he didn’t know of any, and he wasn’t going to experiment with his own! So it was himself, Andrew, and Dezi.

Andrew, a little while later, when Damon broached the subject, frowned and said, “I can’t say I’m crazy about the idea of working with Dezi.” But, at Damon’s remonstrance, admitted it was hardly worthy of an adult, to hold a grudge against a boy in his teens, a youngster who had, admittedly, been drunk at the time of the offense.

“And Dezi’s young for his age,” Damon told Andrew. “If he’d been acknowledged nedestro, he would have been given responsibilities to equal his privileges, all along. A year or two in the cadets would have made all the difference, or a year of good, hard, monkish discipline at Nevarsin. It’s our fault, not Dezi’s, that he’s turned out the way he has.”

Andrew did not protest further, but he still felt disquiet. No matter whose fault it was, if Dezi had flaws of character, Andrew did not feel right about working with him.

But Damon must know what he was doing. Andrew watched Damon making his preparations, remembering when he had first been taught to use a matrix. Callista had been part of the linkage of minds then, though she was still prisoner in the caves, and he had never seen her with his physical eyes. And now she was Keeper no more, and his wife…

Damon held his own matrix cradled between his hands, finally saying aloud, with an ironic smile, “I am always afraid to do this outside a Tower. I never lose the fear that it is not safe. An absurd fear, perhaps, but a real one.”

Dezi said gently, “I am glad you are afraid too, Damon. I am glad to know it is not only me.”

Damon said, in a shaking voice, “I think anyone who is not afraid to use this kind of force probably should not be trusted with it at all. The forces were so misused in the Ages of Chaos that Regis Hastur the Fourth decreed that from his day, no matrix circle should presume to use the great screens and relays outside the established Towers. That law was not made for such work as this, but there is still the sense of… of violating a taboo.” He turned to Andrew and said, “How would they treat frostbite in your world?”

Andrew answered thoughtfully, “The best treatment is arterial injection of neural stimulators: acetylcholine or something similar. Possibly transfusion, but medicine isn’t really my field.”

Damon sighed and said, “I seem to have been thrust into such work more often than I intended. Well, let us get on with it.” He let his mind sink deep into the matrix, reaching out for contact with Andrew. They had been linked before, and the old rapport quickly reestablished itself. For a moment there was a shadow-touch from Ellemir, only a hint, like the faint memory of a kiss, then she dropped gently out of the rapport at Damon’s admonition: she must guard her self and their child. For an instant Callista too lingered, a fragmentary touch, in the old closeness, and Andrew clung to the contact. For so long she had not touched even his hand and now they were linked together, close again — then, with : poignant sharpness, she broke the link, dropping away. Andrew felt empty and cold without the touch of her mind, and he sensed the wrenching aftertaste of grief. He was glad, for a moment, that Dezi was not yet in the rapport. Then Damon reached out and Andrew felt Dezi in the linkage, was momentarily aware of him, barriered, yet very much there, a cool firm strength, like a handclasp.

The threefold link persisted for a moment, Damon getting the feel of the two men with whom he must work so closely linked. With his eyes closed as always in a circle, he saw behind them the blue crystalline structure of the matrix gems which held them linked together, amplifying and sending out the individual, definite, electronic resonances of their brains, and beyond that, the purely subjective feel of them. Andrew was rocklike and strong, protective, so that Damon felt with a sigh of relief that his own lack of strength did not matter, Andrew had plenty for both of them. Dezi was a quick, darting precision, an awareness flicking here and there like reflections of light playing from a prism. Damon opened his eyes and saw them both; it was difficult to reconcile the actual physical presence with the mental feel within the matrix.

Dezi was so much — physically — the image of Coryn, his long-dead friend, his sworn brother. For the first time Damon let himself wonder how much of his love for Ellemir arose from that memory, the brother-friend he had loved so deeply when they were children, whose death had left him alone. Ellemir was like Coryn, and yet unlike, uniquely herself — He cut off the thought. He must not think of Ellemir in this strong link or he would be picking her up telepathically, and this strong rapport, this flow of energons, could overpower and deform their child’s developing brain. Quickly, picking up the contact with Dezi and Andrew, he began to visualize — to create on the thought-level where they would work — a strong and impregnable wall around them, so that no other person within Armida could be affected by their thoughts.

When we work with the men, healing them, we will bring them one by one behind this wall, so that nothing will overflow to damage Ellemir or the child, or trouble Callista’s peace, or disturb the sleep of Dom Esteban.

It was only a psychological device, he knew, nothing like the strong electrical-mental net around Arilinn, strong as the wall of the Tower itself, to keep out intruders in body or mind. But it had its own reality on the level where they would be working: it would protect them from outside interference, shielding those in Armida who might pick up their thoughts, and dilute or distort them. It would also focus the healing on the ones who needed it.

“Before we start, let’s have it clear what we’re going to do,” he said. Ferrika had some rather well drawn anatomical charts. She had been giving classes in basic hygiene to the women in the villages, an innovation of which Damon completely approved, and he had borrowed the charts she used, discarding the ones she used to teach pregnant women, but keeping the one which diagramed the circulation. “Look here, we have to restore circulation and healthy blood flow into the legs and feet, liquefy the frozen lymph and sluggish blood, and try to repair the nerve fibers damaged by freezing.”

Andrew, listening to the matter-of-fact way in which Damon spoke, in much the same way as a Terran medic would have described an intravenous injection, looked uneasily at the matrix between his hands. He did not doubt that Damon could do everything he said he could, and he was perfectly willing to help. But he thought they were a most unlikely hospital team.

The men were lying in the room where they had been taken. Most of them were still in their drugged sleep, but Raimon was awake, his eyes bright with fever, flushed and pain-racked.

Damon said gently, “We have come to do what we can for you, my friend.”

He bared the matrix in his hands; the man flinched.

“Sorcery,” he muttered, “such things are for the Hali’imyn…”

Damon shook his head. “A skill which anyone with the inborn talent can use. Andrew here is no Comyn-born, nor of the race of Cassilda, yet he is skilled in this work, and has come to help.”

Raimon’s feverish eyes fixed on the matrix. Damon saw the twisting sickness pass over his face, and even through his own growing euphoric rapport with the jewel, he somehow found enough separateness and detachment to say gently, “Do not look directly into the matrix, friend, for you are not trained to the sight, and it will trouble your eyes and brain.”

The man averted his eyes, making a superstitious gesture, and Damon felt annoyed again, but he controlled it. He said, “Lie down, try to sleep, Raimon,” and then, firmly, “Dezi, give them another dose of Ferrika’s sleeping medicine. If they can sleep while we work, they will not interfere with the healing.” And if they slept, they would feel no fear, and thoughts of fear could interfere with the careful, delicate work they would be doing.
