“Mara’s miniature universes are quite irrelevant to Mr. Chesney,” Querida stated. “Be warned, Wizard Derk. Either you present yourself at Derkholm to Mr. Chesney and the rest of us tomorrow, or you have every magic user in this world looking for you to make you be Dark Lord. Do I make myself clear?”

Blade pulled his father’s arm. “Better go, Dad.”

“And you, young man,” said Querida. “You’re to be there, too.”

Blade succeeded in pulling his father around sideways, but Derk still looked down at Querida across his own shoulder. “No one should have this kind of power,” he said.

“To whom do you refer, Wizard?” she asked, still in her cobra stance.

“Chesney, of course,” Derk said rather hastily.

Here Blade pulled harder, and the two of them disappeared in a stinging cloud of blown sand.

“Phew!” said Barnabas. “Poor old Derk!”

“Let us go home more slowly,” said Querida. “I feel a little tired.”

The return journey was more like a lingering walk, in which they trod now on a patch of hot sand, now on wiry dead grass, now on rocks or moss. Regin put himself beside Querida as they went. “Who is this Wizard Derk?” he asked.

Querida sighed. “A shambles of a man. The world’s worst wizard, to my mind.”

“Oh, come now, Querida,” said Barnabas. “He’s excellent at what he does—just a little unconventional, you know. When we were students together, I always thought he was twice as bright as me.”

Querida shuddered. “Unconventional is a kind word for it. I was senior instructor then. Of all the things he did wrong, my worst memories are of being dragged up in the middle of the night to deal with that vast blue demon that Derk had called up and couldn’t put down. You remember?”

Barnabas nodded and bit his lip in order not to laugh. “Nobody knew its name, so none of the usual exorcisms worked. It took the entire staff of the University to get rid of it in the end. All through the night. Derk was never much good at conventional wizardry, I admit. But you use him a lot, don’t you, Reverend?”

Umru smiled sweetly, his fat, comfortable, cool self again. “I pay for Wizard Derk’s services almost every time my temple has a tour party through. No one but Wizard Derk can make a convincing human corpse out of a dead donkey.” Regin stared. Umru smiled ever more sweetly. “Or a sheep,” he said. “We are always chosen as an evil priesthood, and the Pilgrims expect us to have a vilely tortured sacrifice to display. Wizard Derk saves us the necessity of using people.”

“Oh,” said Regin. He turned to where King Luther was trudging grimly in the rear. “And you, Your Majesty? You know this wizard, too?”

“We use him for hangings and heads on spikes occasionally,” King Luther said. “But I hire him most often for the feast when the damn Pilgrims have gone. He has performing animals. Pigs mostly.”
