At night, you're at a camp, with nothing but your friend, the supplies, and a low amount of food and resources. You guys were traveling, and so we made camp. It was a cold blizzard, and after the invasion of their neighborhood from that blizzard, they had ran. The friend decides to scavenge for firewood when you're returning to camp to sleep, but the next morning he hadn't returned. You waited for him until night came. A ghoul would kill them.
