Isaac walked steadily along a rocky cliffside. From what he had heard in the settlement he had just came from, the group of raiders he was tracking were last seen heading towards vault 200. The vast resources and often inexperienced occupants of vaults made them tempting targets for raiders, though they were rarely able to get past the vaults door. He figured that the group would likely be stuck in that exact way, and would be easing pickings from this ridge overlooking the vault. Rounding a cliffside corner, he saw the circular frame of the vault come into view, but to his surprise the gear shaped door itself was open. 

"Shit, was I too late?," he muttered to himself. He took his hunting rifle off of his back and laid prone on the stone, pointing his gun towards the ajar door. 

Gazing through his scope he studied the vault entrance. There was no movement, but looking into the vault he spotted a few limp corpses lying within the entrance. They had definitely been here. Now the question was, were they still inside? Closer inspection would be needed to find that out. 

Just as Isaac was getting up to climb down the stony hill, a burst of movement came from within the vault. Quickly steadying himself again, Isaac tracked the figure in his lens. It was a young woman, and she frantically charged forward into the the light before collapsing to her knees. Her blue vault suit gave her away as a survivor. She sat there in the dirt, apparently sobbing. As he watched her, Isaac felt a cocktail of emotions begin to boil in his chest. Anger at the raiders for destroying the lives of the vault dwellers, frustration towards  himself for not arriving sooner, but mostly guilt. He didn't have to be close to the girl to tell that she was unprepared for the devastation of the outside world, many vault dwellers are, but even from this distance he could feel that she was especially innocent. Her tears were not just for the devastation of her vault, but for the undoing of the world as she knew it.

 While he contemplated these feelings, he saw something approaching her in the wastes. Were the raiders back for more? No, this thing was moving on all fours, and coming straight at her. He adjusted his scope, and took aim at the charging creature. As it closed in, he wrapped his finger around the trigger, but hesitated. It wasn't a wasteland beast that came towards her, but a dog. Dogs can still be dangerous of course, but this one appeared to comforting her instead of attacking. After a minute, she stood up and set off into the dust, dog in tow. Isaac's guilt and frustration were quickly replaced with panic. Charging into the wasteland unprepared rarely ended well for anybody. Getting down from the hill he was on would slow him down, but if he hurried he could hopefully catch up with her before she got into too much trouble.
