Prison

Darkstalker was already snapping a branch off one of the trees overhead.
“Branch,” he commanded, “grow into a fine, strong, indestructible prison, with room for at least ten prisoners, that no dragon could ever break out of.”
He flung the branch down toward the ground, and as it fell it began to grow, snapping outward and up, smashing through everything it hit as it plummeted. When it finally crashed to earth, far below them, it was a massive, dense cube of some unfamiliar material, with no windows. The last few blocks slammed into place, and then it fell silent, apparently finished.
The RainWings all stared down at it. Turtle could see Kinkajou leaning over the edge of the walkway outside the healers’ hut, her face a picture of outrage.
The prison was gray and solid, large and forbidding. It hulked on the rainforest floor like a sinister cloud that had been dragged to earth and chained down. Everything about it exuded wrongness.
“Perfect,” said Darkstalker. A ring of metal keys had appeared in his talons, and he tossed them to Queen Glory. “You’re welcome.”
