"Go bring that soul back here," The voice spoke.
All of a sudden, a black thread shot forth inside the cave. This black thread quickly wove itself into a round ring in mid-air, and then the center of the ring slowly split apart, forming a mirror inside.
The surface of the mirror was as bright as new, and it slowly began to reflect a line of white Dragon Whelps. There were four of them, hiding inside a cave and chatting idly.
The green flames in the Knight's eyes flickered for a moment, and then they instantly locked onto one of the Dragon Whelps.
This white dragon was well-proportioned, with strong muscles and scales that seemed brighter and cleaner than the other white dragons.
It bowed toward the depths of the cave and then turned around and walked out of the cave, clattering as it went. There was an extremely complex golden screen turning slowly at the mouth of the cave, blocking off all the threats that might walk out of the cave.
