the world went to shit 5 years ago, international disputes, resource wars and the crash of almost every single global economy drove the entire population to anarchy. Cities are left abandoned, factions form and factions fall, there is no law in this new world, the rich and the lucky find themselves sealed off in bunkers, able to hide from the worlds problems. You are neither rich, not lucky
(you have spent the last two years of your life in a vast forest, you've setup camp in a fire watch tower with solar panels on the roof, there's plenty of wild animals to hunt and berries and herbs to scavenge. There's a river 1.5km south from the fire watch tower where you can fish, your life is quite solitary, you have a small weapons stash but you only ever use it for hunting, very few people find their way out to this massive forest)
You find yourself sitting at the bottom of the fire watch tower, you've set up tall fences with barbed wire to deter any person looking to intrude, you're sitting on an old lawn chair as the sweet evening air blows throughout the forest, some cured cuts of venison from a dear you hunted a few days prior sizzle on the old barbeque grill that you finally got working along with a few small fish you caught today
It's a solitary lifestyle you live, but it's peaceful... An you don't have to worry about killing other humans, betrayal, loss, or any personal problems. You have your hunting rifle, your fishing rod and your grill... And a fantastic vue from he fire watch tower.... Some of the nearby animals even feel safe around you and don't mind getting close to you or asking for spare scraps of food. How. Relaxing...
In the distance you hear a shriek that's sends shivers down your spine
