Summary
As always whenever the Courier gazed at the eclectic collection of killing machines, they wondered what the stories behind the weapons were. A good majority of the items were procured off of dead bodies they had stumbled across on their various quests, and there was never a conveniently placed terminal or notebook telling them the lore of the dead.
Sighing to themselves, they turned back to the terminal, writing down possible leads they had thought of throughout the day...
(A collection of one-shots based around the unique weapons you can find in Fallout: New Vegas).
