Man came technologically, and brought the infectious seed of science with him. He set about colonizing the planet, calling it Proton, burning its forests and slaughtering its creatures. The animals had never been exposed to the horrors of science, and though they tried to fight back, they were being decimated. The goblins mounted a savage counterattack, wiping out several colony settlements, but the humans reciprocated by bombing the goblins’ camps and warrens and nearly wiping out several tribes. It was evident that all too soon the creatures here would go the way of their cousins on Earth.
But not all the invaders were vicious or uncaring. Some few appreciated the nature of Phaze and sought to preserve its unique environment. These managed to deal with the elves to create a barrier between the frames of science and magic, separating them. This had an immediate effect, because the weapons based on science no longer worked in the magic frame, and magic no longer worked in the science frame. It effectively isolated the two factions, though they actually shared the territory. They were out of phase with each other. This was the origin of the name of the magic realm: Phaze.
Then a peculiar effect manifested. The two frames assumed an equivalence in more than geography. Human beings who were born and raised on the planet began appearing on either side of the curtain, mirror images of each other. In some interaction between science and magic they had cloned, the parties on either side living similar lives, but utilizing different modes. It was possible for newcomers to the planet to cross the curtain, though not always easy. Clones could not; the presence of their other selves barred them. Thus the frames were increasingly separated. But this meant that only those who knew least about the opposite frames could cross to them, and this meant trouble.
Some long-time residents developed formidable powers of magic, and became known as Adepts. The potential for magic was in every creature, but the Adepts acted ruthlessly to restrict its application. Those whose powers were less soon learned to avoid the use of magic almost entirely, so as not to seem in any way competitive with the Adepts. They settled into innocuous village life, while the Adepts became like distant lords. The Adepts took it upon themselves to protect Phaze from unwarranted intrusions across the curtain, using magic to detect and eliminate most of those who crossed.
But the Citizens of the developing hierarchy of Proton were in no mood to brook such interference with their rights of exploitation. They used their computers to prepare an exhaustive analysis of the mechanisms of magic, and developed a computer that could invoke this magic without error or waste. Because a computer could not operate in Phaze, they digested these principles into a comprehensive Book of Magic that any person could use with devastating effect. The conquest of Phaze by Proton was about to resume. This of course was incipient disaster, and the more sensible elements of both cultures opposed it implacably.
A compromise was achieved: the Book of Magic was confined to Proton and hidden, so it could not be used, and the computer was put across the curtain into Phaze, where it was given limited animation as the Oracle: an entity that would answer any question once. References to Phaze in the literature of Proton were extirpated, and in a generation it was as if the other frame did not exist. But the Citizens knew of it, and some of their secretaries learned. Surreptitious crossings still occurred, but there was a conspiracy of silence about the matter. The Citizens who had other selves in Phaze could not cross, and did not want others to do so.
So it was for three hundred years—until the extensive mining of Protonite in the science frame generated an imbalance that threatened to tear the fabric that separated them and destroy both. The Oracle understood this, but could not act directly to alleviate it. Its only power was answering questions directed to it, and not many of those. Therefore it used that power to cause the Blue Adept to be murdered—
Bane snapped out of the vision. “What?”
“You have assimilated the history of the frames,” the Oracle said.
“Thou didst cause Blue to die?” Bane demanded.
“Only one person seemed likely to be able to do the necessary job,” the Oracle replied. “That was Stile, in the frame of Proton, the Blue Adept’s other self. He knew nothing of Phaze, and could not cross. Therefore I devised a plan to free him for crossing, and to acquaint him in due course with this mission. This is a story whose general gist you may already know.”
