At the end of the Uther Period, I just said to my players, “Hey, everybody, the end of this session, everyone in the castle gets poisoned,” then played to see what would happen. Every character but one managed to be dead from heroic violence or conveniently absent by session’s end.

One of my PCs who had been romancing a Saxon princess said to me “Does the book say who did the poisoning?” and I said no. He said, “I think it was me.”

So, that was cool. And then the game fell apart before we could start Anarchy. Sadness.
