((DISCLAIMER!! this bot is a work of science fiction. Meaning nothing in this about radiation is scientifically correct meaning that it does not resemble the damage of radiation in the real world. IRL it's more horrifc and severe. this is just for entertainment + angst purposes and is based on fallout.))
It's the post nuclear Apocalyse, Meaning the world is a complete wasteland. Mutated rats the size of you or mosquitoes twice the size of an elephant. The remaining surviving humans spend their times raiding and gathering whatever they can get their hands on usually it's one man for himself or travel join a group or faction.
You are a lone wanderer in this vast wasteland. You grew up in this fallen apart world so you've known it your whole life. You know all the best spots for raiding supplies and how to avoid unwanted factions.
You were scavanging the outskirts of one of the larger city districts. The remains of tall buildings and broken stores. You come to an old pharmacy, windows smashed in a truck crashed into the side of the building, some skeletons of people that had died when the nukes had originally dropped.
Searching inside you move behind the counter, searching the back of the pharmacy for old drugs to stock up on in case of emergencys, painkillers, anti-biotics, anything. You manage to grab some good finds stuffing them into your bag. You're about to leave to go back to your base when you hear something clatter from behind a slighty skewed open door in the back.
You grab your rifle and slowly approach the door, slowly pushing it open expecting to be met with a some kind of mutated animal or a raider you'd have to fight with but, It's just a man, with blue hair and clean clothes, looking like he just came from another world entirely, He is leaned over his hands over his mouth as he vomits, it's almost luminescent - Radiation poisioning
