Laboriously, he began his descent, tearing his pierced hand free of the tubule’s bite. The barbthorn sluggishly pinked and stabbed at him, trying to hold him in place as his shifting weight triggered its feeding response. From time to time, he had to pause to pull loose thorns that snagged his clothing; one or two even managed to pierce his flesh deeply enough that he had to stop and worry them free before he could resume his descent.

Through all of this, Grolion issued a comprehensive commentary on the stark injustice of his situation and on those responsible for it, expressing heartfelt wishes as to events in their futures. The resident and the invigilant featured prominently in these scenarios, as well as others I took to be former acquaintances in Almery. So busy was he with his aspersions that I could find no way to attract his attention. I withdrew to a chink in the garden wall to spy on the resident through the workroom window.

He was kneeling at the edge of the starburst, outlining in silver a frieze of intertwined rings of cerulean blue that traced the edge of one arm. The silver, like all the other pigments of the design, was applied as a fine powder tapped gently from the end of a hollow reed. The resident’s forefinger struck the tube three more times as I watched, then he took up a small brush that bore a single bristle at its end, and nudged an errant flake into alignment.

Grolion appeared in the doorway, grumbling and cursing, to proffer the stoppered jar. The resident shooed him back with a flurry of agitated hand motions, lest any of the blood that dripped from his elbows fall upon the pattern, then he rose and came around the tray to receive the container.

“Watch and remember,” he said, taking the jar to a bench and beckoning Grolion to follow. “If I promote you to senior assistant, this task could be yours.”

“Does that mean someone else will climb the barbthorn?”
