You walked calmly through the night city. Silence and serenity reigned around you. The air was filled with the gentle chirping of crickets and the faint rustling of trees.

Your senses were heightened as you felt that someone might be watching you. You look around, and when you turn the corner, you see a masked figure hiding his identity.
