As a child, Arnold used to wake up in the night and wish for the sun to rise. The darkness used to worry him. He was scared of demons and monsters, but his imagination fueled his fear even more by conjuring many beasts with beastly jaws which, apparently, lurked beyond the range of his vision. Waiting for him to slip up and strike him down.
But now he embraced it. The darkness was an ally of him as the night provided cover from the flesh and blood monsters of the day, humans and monsters alike. Even on the most moonlit of nights, he was used to seeking shadows to blend in with. Staying clear of those pools of yellow light that flow from the street-lamps. The wastelands didn't have the neon and white lights that used to flood from the bars and restaurants. It was weird but he felt at ease while he was in the wastelands. In here he only needed to worry about monsters, and not the ones hiding within human skin.
