The Flame of Hatred
Back to Novigrad
Just to the east of the Hierarch Square you’ll find a man preaching in the street. He condemns the mages, alchemists and witchers. When you get close to him he’ll start insulting you. Talk to him and you can either ask him how many lives he’s saved, threaten him or leave. Whichever option you choose the crowd will disperse and you’ll earn a few XP.
A few days later if you come back to the same area a couple of Guards will question you and tell you that you must hand over your weapons. Handing over your weapons is a bad idea as they’ll reveal they’re from the Preach and want revenge for humiliating him. Finish off the thugs and the quest will end.
