Colin wiped a bead of sweat from his forehead and closed the book shut.  He could feel his powers functioning better then usual.  With a grin he stepped away from the circle.  He could see the energy fields around him, as was part of his gift with magic.  He walked along through the forest, watching the energy fields for a disruption.  At least he found it, and walked towards it.  He could hear voices up ahead, and he pressed on, preparing for anything.  His magical wards were up and his mental barriers in place.  He walked forward and through the trees, to spot an unexpected group of people.  "Where did they come from.." He whispered to himself, crouching behind one of the trees to watch.
