Arkain rubs his chin watching you study the root. "Hmmmm. No your right. They don't." Then he looks around at the trees and his expression drops and looks very nervous. He quickly stands up and looks all about like he is expecting something to jump out. "Yea. It's proof alright. Solid roots springing out of the ground is not something I consider very ghostly. Its proof we need to get out of here now! Last time I saw roots move like that we found out we were in a forest protected by magic. Before we knew what happened roots suddenly sprung up and two of my traveling companions were dragged away into the forest. We never saw them again. We are sure the trees got them because the rest of us had to fight our way past grabbing roots and branches. We barely got out alive. I could be wrong but I don't to find out. You found some proof. Great. Now lets get the heck out of here."
