Collecting, and harboring, cursed artifacts is a dangerous game.
One always runs the risk of curse transference!
And then innocent people may suffer as you are Fulfilling The Curse!
FULFILLING THE CURSE
They are known in arcane circles of magic and evil as The Dead Man's Gun!
There have been many versions of this most profane of firearms.
They are infused with an evil curse that turns the owner into a homicidal serial killer.
I love to clean and polish my Dead Man's Gun... after I fulfill the curse every night!
