The Prince drew himself up with hauteur. "One favor ye did me, yet ye presume to impose on me for two favors! I need no stricture of cohabitation for when I come of age-not when I have the entire world of harpies to build my harem from. As to this spell, I know naught of it."
"It happened after your exile. You can discover its nature from your subjects."
"I shall do so," the harpy said. "An I discover it, I shall provide the counter as your recompense."
Dor conducted the Prince to King Roogna, who did a polite double take as he observed the harpy's gender. "Rare magic indeed!" he murmured.
"We must release Prince Harold Harpy to his kind without mishap," Dor told the King. The harpies will have no need to fight, once they have him."
"I see," the King said. He glanced obliquely at Magician Murphy, standing beside him. "We shall declare an absolute cease-fire until he is free, I shall walk the ramparts myself, to be sure that nothing goes wrong."
"You may manage to free the harpy," Murphy said grimly. "But my curse will have its impact elsewhere. You have not prevailed." But he looked tired; his talent was evidently under severe strain. No single Magician, however gifted, could stand forever against the power of three. Dor was almost sorry for him.
"But we're getting there," Roogna said. He escorted the Prince to the wall, cautioning the centaurs not to fire at the harpy. Prince Harold spread his pinions and launched into the sky.
There was a screech of sheerest amazement from the nearest female. Then the harpies swarmed to the Prince. For an awful moment Dor feared they had mistaken him, and would tear him to pieces; but they had instantly recognized his nature. They lost all interest in the goblin war. In moments the entire swarm had flapped away, leaving the goblins nothing to fight except a few tired vampires.
Then a lone female harpy winged back from the flock. A centaur whistled. "Helen!" Dor cried, recognizing her.
"By order of Prince Harold," Helen said. "The counterspell." She deposited a pebble in his hand. She winked. "Too bad you didn't take your opportunity when you had it, handsome man; you will never have another. I used the ring you gave me to wish for the finest possible match, and now I am to be first concubine to the Prince." She tapped her ringed claw.
Things evidently happened fast among the harpies; it had been only a few minutes since the Prince mounted the sky. "Good for you," Dor said.
"I knew I could do it," the ring replied, thinking Dor had addressed it. "I can do anything!"
She glanced down at it "Oh, so you're talking again!"
"It will be silent hereafter," Dor said. "Thank you for the counterspell."
"It's the least I could do for you," she said, inhaling. The centaurs goggled.
Then Heavenly Helen spread her pretty wings and was away, with all males on the parapet staring after her, and even a few of the healthier zombies were admiring her form. There were covert glances at Dor, as people wondered what he had done to attract the attention of so remarkable a creature.
Dor was satisfied. Helen had, in true harpy fashion, snatched her opportunity. And who could telclass="underline" maybe the wish ring really had had something to do with it.
Dor turned his attention to the pebble spell. "How are you invoked?" he asked it.
"I am not invoked; I am revoked," it replied. "I am not a counterspell, I am the original spell. When I am revoked, the enchantment abates."
"How are you revoked, then?"
"You just heat me to fire temperature, and my magic pours out invisibly until it is all gone."
Dor handed the pebble to the King. "That should abate the goblin complaint. With no further reason to fight, the goblins should go home. Then Murphy's curse can't make the battle continue here."
"You are phenomenal, Magician!" King Roogna said. "You have used your mind instead of your body, in a truly regal manner." He hurried away with the pebble spell.
The King cooked the goblin spell according to the directive, but no change in the goblin horde was apparent. Yet he was not dismayed. "The original spell was subtle," he explained. "It caused the goblin females to be negatively selective. The damage has been done to the goblins over the course of many generations. It will take many more generations to reverse. The females are not here on the battlefield, so the males do not even know of the change yet. So we do not see its effect immediately, or benefit from it ourselves, but still the job is worth doing. We are not trying merely to preserve Castle Roogna; we are building a better Land of Xanth." He waved a hand cheerfully. "Evening is upon us; we must go to our repast and sleep, while the zombies keep watch. I believe victory is at last coming into sight."
It did look that way. Magician Murphy looked glum indeed. Dor, suddenly tired, ate perfunctorily, fell on the bed provided in the completed section of the Castle, and slept soundly. In the morning he woke to discover the Zombie Master on an adjacent bed, and Magician Murphy on another. Everyone was tired, and there was as yet very little space within the Castle.
The goblins had largely dispersed in the night, leaving their copious dead in the field. The zombies remained on guard. The centaurs had resumed their building labors, no longer needed for the defense of the Castle. Now it did seem likely that Castle Roogna would be completed on schedule.
A buffet breakfast was being served in the dining hall, amid the clods of earth, stray pieces of zombies, and discarded weapons. King Roogna was there, and Magician Murphy, and Vadne and Jumper and Dor. Murphy had little appetite; he seemed almost as gaunt as the Zombie Master.
"Frankly I think we have it in hand," the King said. "Will you not relinquish with grace, Murphy?"
"There remains yet one aspect of the curse," Murphy said. "Should it fail, then I am done, and will retire. But I must hold on until it manifests."
"Fair enough," Roogna said. "I hung on when it seemed your curse had prevailed. Indeed, had not young Dor arrived with his friend-"
"Surely nothing I did really affected the outcome," Dor said uneasily. For there, ultimately, could be Murphy's victory.
"You still feel that what you do is invalid?" the King inquired. "We can readily have the verification of that. I have a magic mirror somewhere-"
"No, I-" But the King in his gratitude was already on his way to locate the mirror.
"Perhaps it is time we verified this," Murphy said. "Your involvement, Dor, has become so pervasive and intricate that it becomes difficult to see how it can be undone. I may have been mistaken in my conjecture. Was my curse opposing you also?"
"I believe it was," Dor said. "Things kept going wrong-"
"Then you must have validity, for otherwise my curse would not care. In fact, if your efforts lacked validity, my curse might even have promoted them, so that they played a larger part in the false success. If the King depended on you instead of on his own-"
"But how can I change my own-" Dor glanced at Vadne, then shrugged. He could not remember whether she knew about him now or did not. What did it matter, so long as Millie remained innocent? "My own past?"
"I do not know," Murphy said. "I had thought that would be a paradox, therefore invalid. Yet there are aspects of magic no man can fathom. I may have made a grievous error, and thereby cost myself the victory. Is the Gap forgotten in your day?"
"Yes."
They mulled that over for a while, chewing on waffles from the royal waffle tree. Then Murphy said: "It could be that spots of history can be rechanneled, so long as the end result is the same. If King Roogna is fated to win, it may not matter how he does it, or what agencies assist. So your own involvement may be valid, yet changes nothing. You are merely filling a role that some other party filled in your absence."
