Hand of Fate. Part 1: On the March

So, where can I find the "sword of power"? I've searched all the available locations, but I can't find it:confused:

Yeah, by the way, I also couldn't find this sword. I destroyed everything up to the monks; I know about the quest, I've searched everywhere, but I couldn't find it. Maybe I didn't search well enough. There was also an idea that it might drop in the Witch Tower at the bottom or in the crypt, but it didn't. By the way, I defeated the monks later; the mummies with their forgetfulness helped, but it took me about 3 months. I got a little further, and then there were already legions.
