Behind them glowed the two outer crystals of the sky-bridge.

The crystal glowed, it burned bright white, it did not hurt him, though she could feel its great heat.

The crystal glowed, but they paid it no heed as heated looks passed between them.

Gentle words of love were murmured, and the blue crystal glowed softly under its covering.

Without warning the green crystal suddenly glowed brightly for a fraction of a second, then could not be seen at all.

The crystal glowed, then the guard looked back at me, smiled, and said, "He'll be with you in a moment."

The crystal glowed a strong green as he pointed it at the craft.

Not all the crystals in the dome glowed with the same intensity.

The crystals glowed, clear and blue in their shining silver setting.

As it did so he felt a faint electric shock, and the blue crystal in his hand glowed like a spark.
