Whipping Wisps

"Is it difficult to go past it?" Damien asked. 

Serena sighed and nodded heavily. She squinted her eyes as if she were trying to see through the thick thatching of the leaves. She stated in a calm voice, "The Whipping Wisps is enchanted by elf magic. It stops anyone who enters the forest; even when the elves abandon the forest, these trees would still protect the land as if the master was still living in the forest." 

"If I had known that this forest was actually land abandoned by the elves, I would have brought some orc's blood; that way we would have gotten past this hurdle," Sam said with a frown. 

While the rest were worrying about how to cross this hurdle, Damien was trying to find a weakness of the enchanted tree. If he could find the weakness of a beast, then he could certainly find the weakness of an immobile tree.
