Re: Most Obscure Reference You've Ever Worked Into a Game
At the climax of an old Amber campaign, during a major battle between the forces of good versu... who am I kidding, Amber versus Amber, the player characters had one huge advantage. Benedict (ultimate unstoppable warrior) was one NPC who was definitely on their side.
Naturally as evil GM I had to even the odds and leave the PCs to win the day, so I had the lead NPC sorceror on the other side, just before battle was joined, create an illusion of a feisty woman standing just in Benedict's peripheral vision and berating him in no uncertain terms.
He was actually distracted - something unthinkable - just as the sorceror's follow up attack spell struck him - and took him straight out of the fight, him collapsing with the word "Beatrice-" on his lips.
Now none of my players knew much Shakespeare and certainly didn't know that one of the great romances (IMHO) was between Beatrice and Benedick (ok so Shaxberd couldn't spell...) who was at the time just a young soldier... But it satisfied my sense of the obscure.
