Uhm if I'm correct was it the black death?
In our world's history yes. Correct! Now that the plague arc has finished, I can say that while similar to our black death, it is not in which the bacteria have been modified. The biggest spoiler that kept me from talking about it is that the bacteria had been magically + scientifically modified. You can infer this by Roland and Nightingale's reaction as well as the revelation of the church keeping
"useful" witches instead of just turning them all into fuel for their powerful zombie army.
Roland is getting the labor force he desperately needs to ramp up production and eventually start his own industrial revolution. But black spots?! How scary~ Does it remind you of anything in our world's history?
