*TREMBLE!*
With a small tremor that shook the whole mountain, behind Greg and Joe, the split started to close slowly.
Immediately as the exit has been sealed, darkness fell onto the two, making Greg to activate his Second Flow to create light.
However, just before he could have done it, above his head, Greg noticed as small crystals started to shine, and slowly the whole path got lit up with beautiful colorfulness.
"What are these crystals? They can glow with such strong light, that it's amazing!", said Greg as he touched a crystal on the side gently.
"They are called Dusk Stones. By absorbing the darkness in their proximity and transforming it, they can create light and glow like this. They are indeed amazing."
"Dusk Stones, can I take a few with me?", asked Greg curiously, thinking that maybe they could come in handy once.
