The guard went. In moments, they heard water being pumped into a bucket he had found in the butler's cupboard.
Flagg was speaking again.
"I propose to dip my finger into this bucket and let a drop of water fall into one of those holes," he said. "We'll watch this closely, Lord Judge-General. We must see if the water which goes into the hole turns momentarily green. It's a sure sign."
"And then?" Peyna asked tautly.
The Home Guard returned. Flagg took the bucket, set it on the desk.
"Then I'll put drops very carefully into the other two holes," Flagg said. He spoke calmly, but his normally pallid cheeks were flushed. "Water won't stop Dragon Sand, it's told, but it'll hold it." This was making things quite a bit worse than they were, but Flagg wanted them frightened.
"Why not just douse it?" one of the guards blurted.
Peyna favored this upstart with a horrible glare, but Flagg answered the question calmly as he dipped his pinkie finger into the bucket.
"Would you like me to wash those three grains of sand out of the holes they've made in the rock and somewhere onto the lad's desk?" he asked, almost jovially. "We could leave you in here to put out the fire when the water dried up, sirrah!"
The guard said no more.
Flagg drew his dripping finger out of the bucket.
"Water's warm already," he said to Peyna, ` just from sitting on the desk."
He carefully brought his finger, from which a single drop of water hung, over one of the holes.
"Watch closely!" Flagg said sharply, and to Peter he sounded at that moment like a cheap peddler about to perform some monstrously deceiving trick. But Peyna bent close. The Home Guards craned their necks. That single drop of water hung from Flagg's finger, for a moment catching all of Peter's room behind it in perfect curved miniature. It hung... elongated... and dropped into the hole.
There was a spatting hisss, like the sound of grease dropped onto a hot iron skillet. A tiny geyser of steam arose from the hole... but before it did, Peyna clearly saw a cat's-eye flash of green. In that moment, Peter's fate was sealed.
"Dragon Sand, by the gods!" Flagg whispered hoarsely. "Don't, for pity's sake, breathe that steam!"
Anders Peyna's courage was as hard as his reputation, but he was afraid now. To him that single wink of green light had seemed inexpressibly evil.
"Put out the other two," he said hoarsely. "Now!"
"I told you," Flagg said, calmly dipping his pinkie again and staring at the obsidian. "They can't be put out-well, there is one way, the tales say, but only one. You wouldn't like it. Yet we can hold them, and then get rid of them. I think."
He carefully plinked a drop into each of the other two holes. Each time there was a sullen green flash of light, and a plume of steam.
"We're all right for a bit, I think," Flagg said. One of the Home Guards sighed in gusty relief. "Bring me gloves... or folded cloths... anything I can use to pick up this rock. It's as hot as fury, and those drops of water will be boiled away in no time."
Two hot pads from the butler's closet were brought quickly. Flagg used them to grasp the obsidian. He lifted it, careful to keep it level, then dropped it into the bucket. As the obsidian sank to the bottom, all of them clearly saw the water turn a momentary light green.
"Now," Flagg said expansively, "that is well. One of these guards must take this bucket out of the castle, and to the large pump by the Great Old Tree in the middle of the keep. There you must draw a large basin of water, and put the bucket in the basin. The basin must be taken to the middle of Lake Johanna, and sunk in the middle. The Dragon Sand may heat up the lake in a hundred thousand years, but let those that come in that time-if any do-worry about that, I say."
Peyna paused for just a moment, biting his lip in uncharac-teristic indecision, and then he said: "You and you and you. Do as he says."
The bucket was removed. The Home Guards carried it like men carrying a live bomb. Flagg was amused, for all of this was, in large part, magician's foolery, as Peter himself had momen-tarily suspected. The single drops of water he had allowed to fall into the holes had not been enough to stop the corrosive effect of the sand-at least not for long-but he knew that the water in the bucket would damp it well. Even less liquid would have served for more of the sand... a goblet of wine, say. But let them believe what they would; in time they would turn against Peter with that much more fury.
When the guards had gone, Peyna turned to Flagg. "You said there was one way the effect of Dragon Sand could be neutralized."
"Yes-the stories say that if it is taken into a living being, that living being will burn in agony until it is dead... and when it is over-the dying-the power of the Dragon Sand also dies. I had meant to test it, but before I could do it, my sample disappeared."
Peyna was staring at him, white around the lips. "And on what sort of living being did you intend to test this damned stuff, Magician?"
Flagg looked at Peyna with bland innocence. "Why, on a mouse, my Lord judge-General, of course."
