The eeriness that enveloped Stonegate City in the day was magnified in the night. Though electricity was still available, most streetlights were broken, leaving those still operational to enhance the creepy atmosphere.
Mark was the kind of person who went outside at night only if it was absolutely necessary. Even with people around, he couldn't shake the looming sense of danger that came from the absence of the sun.
That made the desolate streets of Stonegate City all the more unnerving under the veil of darkness. He also felt strangely defenseless while riding a motorcycle through such an environment.
Of course, the fact that he had very little experience with motorcycles added to the lingering fear pulling on the back of his mind, even though he was riding behind someone.
