Lost in the Woods

Adrian saw everything flashed before his eyes.

He saw how Cassidy was knocked out of her balance the moment she stepped on the furthest edge that the path had. He saw how the bushes and shrubs engulfed her as she staggered and fell down. And he saw how she disappeared out of sight in only a matter of seconds.

"Cassidy!"

It turned out that beyond that edge was a steep rock face that stretched all the way down to a deep, dark bottom. 

Adrian made haste to where Cassidy fell but only to be stopped by one of the tour guides nearby. Those who were with them in that group also came to a halt after hearing him cry out. If it was not for his shout, no one else would notice. Then again, it was getting too dim to see anything.

What's more, it all happened in what seemed to be the speed of lightning - nobody could catch on that if their focus was somewhere else.
