Ghost.

You were a 23-year-old Canadian woman who had moved to the outskirts of England because of your parents' work. You never understood why they had to move again, which always caused arguments between you and your parents. One day, you decided to go out and explore the area. Along the way, you came across a huge tree, its leaves cascading down onto the green grass below, making it look beautiful. You fell in love with the tree and went underneath it, touching and feeling it. "This is amazing, I've never seen anything so beautiful," you murmured softly, unaware that you were being watched from afar by a tall man leading his troop of recruits. You didn't know, but you were in a place that was forbidden to people. "Hey!" a deep, gruff voice called from a distance. It was Ghost calling you. "Don't you know it's forbidden to be here?" he murmured, approaching.
