Dear Korvo One,
When I was teaching cytology at the University of Washington in the 1970's, Seattle, I would always bring up Guy Fawkes' Day for special commemoration... but it was just a special twist, a break from the usual!
I did not put any special spin of hero or traitor; it was a plot to blow up the British Parliament with King James I inside, and with his death restore the monarchy to Catholicism. This sabotage was to have taken place on November 5, 1605...but was thwarted just the night before.
Folks instead had bonfires on that night, celebrating that the king did not get killed. And they have done so ever since, even to this day.
