Milo and Arnaud stood motionless, their eyes fixed on the crystal.
The light emanating from it seemed to pulse gently, as if alive. The air around them hummed with an energy they could almost taste.
"Stop the expansion," Taron ordered, his voice cutting through the awed silence. "Close the tunnel, Milo. We need to inform the others about this."
Milo nodded, still dazed by the discovery.
With careful movements, he began to seal the section of the tunnel that led to the crystal, ensuring no one could accidentally access it. As they worked, the crystal's blue glow seemed to call to them, as if it held secrets just beyond their reach.
"What do you think it is?" Milo asked softly, his voice barely above a whisper.
Arnaud shook his head, his eyes never leaving the shimmering surface. "I don't know. But I have a feeling we've just found something very important."
