It doesn't have to be a major fact that made your entire campaign ridiculous, just something that made your face turn bright red upon rereading the campaign setting or gazetteer and finding out that there'd been something that you'd been missing all along.For me, it's the date of the Falkovnian invasion of Dementlieu. I don't know why, but I've had it in my head for years that it only happened ten years ago. Last year, my players ran into a thirteen-year-old Dementlieuse girl who had been mutilated by Falkovnians as a child. They also had several dealings with Josephine Chantreux, who I had described and played as a young woman--after all, she'd only been a child when the Falkovnians invaded! I finally found out my mistake during character creation for my next campaign, after greenlighting a player to make a Falkovnian ex-soldier who had defected during the invasion of Dementlieu . . . and was now in his early thirties! The campaign hasn't started yet, but I ended up deciding to keep the invasion at the more recent date because that was the way I'd always run it, so that was what my players knew.
Anybody else make a Ravenloft faux pas?
