A waster that made his living as a trader and arms for hire.
Jason wears a simple pair of scavenged clothes he found in an overturned car that he covered by a linen bed sheet to form a junky coat that atleast somewhat blends in with the waste. Nearly everything he owns is torn or somewhat damaged except for the .223 pistol he carries which is in surpisingly good shape. As he owns a caravan he carries plenty of goods, like amunition, some grenades, clothin that's in decent condition and a few old firearms.
Only eight years old when introduced to the harsh surface world of the wasteland Jason faced trials that would turn a grown man into a pile of wimpering jelly. He saw the cruel brutality of a world where you lived by the skin if your teeth and the only law was 'an eye for an eye'. He grew used to seing corpses and ghouls everyday he breathed. The harsh reality wrecked his innocence and turned him into the cold man he is today.
When he was sixteen Jason joined a travelling merchant as a hired arm. Before the month was over he was shot at three different occassions and let his employer get shot when he was relieving himself, sleeping or not paying attention. Throughout years this trend would continue and Jason gained the reputation if a bad merc that was cheap. Unbelievably there was a steady flow of cash from his mediocre perfomance which he used to succesfully barter with others and amass a decent caravan, which he hired professional help to protect quite often.
More than twenty years spent in the wastes and Jason had gained a reputation, the name 'Crap Shot Steele' and a caravan of goods. Now all he needed to do was father some children to continue his legacy.
