There are in the Night’s Black Agents rulebook two references to a silver briefcase. It is mentioned in the Mule’s background as something that he or she once smuggled from one side of a border to another. It is mentioned under "other conspiracy structures” that in a “truncated conspiracy” an alien or mutant vampire with a ring of protectors might “move fluidly through Europe killing their enemies, dealing with Russian oligarchs for protection or funds, or chasing a silver briefcase”. Evocative!
I suppose that the writers probably meant one of those moulded aircraft-alloy attaché cases that one associates with pistols, multiple passports, and wads of foreign cash, or perhaps one of those riveted aluminium jobs that usually contain cameras and lenses. But I was immediately moved to wonder about an attaché case of solid sterling silver. It seems very obvious that in a “burned spies v. vampires” campaign an solid silver attaché case must be at least highly suggestive.
So about this silver attaché case: is it smooth and unmarked except for the fittings and a discreet London hallmark, highly polished and gleaming like the brightest mirror you ever saw? Or is it simply covered in grotesque and elaborate ornament in chased repoussé work? Is it an ancient reliquary? Is it — must it remain — uncovered and blatant? Or might it be encased in black leather for a disguise?
Why was the case made of silver? Does that constrain something inside? Or protect it? Or conceal it? And from what?
Why do the vampires and their enemies want it so desperately as to make it the MacGuffin of a truncated campaign? Are its contents something that will give the vampires final victory? Or a weapon that could cause their ultimate defeat? Or both?
Is it soldered shut? Locked? Fastened with a simple catch?
