Speaking of which, has anyone been able to see something like these spirits?

I've been looking around town and climbing things I probably shouldn't have climbed, but I didn't see anything that looked like a spirit. But to be fair, I didn't go into the fog, or go too far down the mines.

[ His sense of danger isn't quite that bad. ]

Also, I'm not saying there has to be one, but whenever I hear the word sacrifice, I think of something like an altar? And I haven't seen anything like that either. Unless the twist is that the entire town is an altar...
