Once Walker knew that the young adventurer group was doing fine, he gave Alice a nod. She knew what he had planned to do since they were nearing the area that the undead ruins were. She knew that Walker wanted to get a closer look at the land around it and discover what had changed.
He had the best mana sense that was within the group. It only made the most sense that he would be the one checking things out. Plus, there were multiple scouts and other hidden figures with the group already. They would be taking care of anything that could cause problems while he scouted ahead alone.
While Walker used the shadow wrapping skill to do this, he left the grove of trees and felt the change immediately.
The distant tower which had been somewhat ominous was left half the size. The remaining had crumbled inward and around but that rubble was unseen from where Walker stood. What he felt though, that was interesting.
