Time is up

"In combination with the Lemurian crystal to levitate something, the amethyst provides a lasting vitality," Elena explained, her voice calm yet filled with excitement. "You may have seen something similar at the construction site where you recently worked. This floating obelisk is a simple design that any sorcerer can create." She paused, a nostalgic look in her eyes. "I actually crafted this piece myself during my apprenticeship cycles ago."
The son gazed in awe, unable to fully comprehend the existence of such a remarkable object right before him, even after touching it in multiple places. Several shattered rocks floated in close proximity to one another, their hollow interiors adorned with a rich layer of rough crystallized substance. A bright purple gem glowed at the center, holding the structure together like an hourglass-shaped formation. When he touched it, the floating pieces seemed to drift slightly, but the core maintained their connection, with his hand feeling the pull of its gravitational force.
As the initial amazement subsided, a sense of sadness washed over the boy. He felt the weight of his own mortal limitations, realizing that he could never achieve something of this magical. However, Elena's warm smile reassured him. "You would be able to do it as well," she said, her voice full of encouragement. The boy snapped out of his momentary despair, catching Elena's words. "How could I...?" he wondered, suspecting that she was mocking his lack of ability to use magic. But Elena's sincere smile persisted.
The son took a step back from the shrine, his voice trembling as he attempted to speak. However, his thoughts were interrupted by the appearance of a guard at the edge of the bushy sanctuary. "Milady, the time is up. The commander summons you, and the boy must return to his room for today," the guard announced politely yet firmly.
