“I hope you are not seeking my aid in reconciling you with Aket-ten,” the Healer drawled. “I am not particularly interested in mending the quarrels of young lovers.”

Kiron flushed. He thought about protesting that he wasn’t Aket-ten’s lover, and thought better of it. If he did protest, Heklatis would only be more certain that he was. And probably tease him about it. The Healer had an acid wit, and was not reticent about exercising it.

“I wanted to ask you about the dust you’re making, and about some other things,” he said, sitting down on a stone bench in the shade. “But first, I want to know about the dust. Is it safe around people? I mean, could I get the disease by breathing it or something? And how are you making it, exactly?”

“Well! Sensible questions! I stand amazed.” Heklatis raised both eyebrows in an exaggerated look of surprise, turned on his side to face Kiron, and propped his head on his hand. “You cannot get the disease; it is a disease of plants. However, because the dust is poisonous in large quantities, you could become ill if you stuck your nose in a bag and inhaled, so I advise against doing anything of the sort. Doing so would also make you liable to lung sickness, which would also make you extremely ill and might kill you.”

So. That meant that to release the dust, they would not want to be in its path or below it until most of it had been carried off. “In that case, the best option would be to carry it in leather bags, cut the bottom of the bag when we get above the storm, and keep climbing, zigzagging back and forth, until the bags are empty.” He nodded. “How are you making it?”

“Ah, now that is a truly interesting question!” Heklatis’ eyes finally lit up with enthusiasm. “We had a small quantity to begin with, and we proved what it did without using more than half of that store. It is related to a fungus very common in the swamp, and what I am doing is this: I have sent slaves to gather the common stuff, and when I have extracted as large a batch as I can manipulate, I magically prepare the batch, then take a pinch of the disease dust and drop it in. And by what we Akkadians refer to as the ‘Law of Contamination,’ the pile of fungus dust is converted to disease dust. Not,” he added, “without great effort, however. The Magi in the Tower have the Winged Ones to draw upon for their storm-magic, for instance; I have only myself, Aket-ten, and now Kaleth. And I refuse to drain my young assistants as the Magi drain the Winged Ones.”

Kiron stared at him in fascination. “Can you make anything into anything else that way?” he asked.
