Where in the world are you talking about? Where were witches "burnt at the stake" in 1794? If you want credibility, you should first try accuracy.
Chosen One of course, does not know her history. The Witch trials were in the 1690s and they represented far less burning at the stake than what transpired in old England. What people may not know is that witchraft, in the 17th century, was a crime against society. There were no witch lobbies arguing against the penal code of the day. Anyone reprobate enough to embrace witchcraft knew what they were in for, and they knew they deserved it.
the most notorious witch trials in the america were in 1692, but in europe during the inquisiton there were witch trials up untill 1792.
