Began playing this quest a few days ago, so far it's really unique and interesting. I really like the idea this quest has, so great job on that.
I have two questions though. For one, what are these for?

And second question, any hints as to where I can find Level 5? I've been wondering around for a little while now, unless it's in a place that is incredibly obvious and I just skipped it a lot like an idiot lol
Either way, I'm definitely looking forward to playing more of this!
Edit: Seems like I didn't look hard enough, found Level 5 lol. I'd still like to know what those two things on the images are though.
Edit 2: Found out those rings on the floor are just whistle whirlwind locations. And new issue, can't find Level 6 anywhere, though I've managed to find Level 7 and 8. I also managed to find a key in that Tropara place, but I dunno if there are any other keys in that area.
