The scenario “A Tear for Ossir”

I found this place and dug it all up (you could have made a cemetery here), but I couldn't find the Tear, even though I was digging in the right place.

Well, that's the whole point! That's why there are signs everywhere and they speak in riddles! The answers are hidden in these riddles ;)

I'm having the same problem with it. I've killed everyone, but I can't finish it.

Of course, because one of the main tasks (finding the Tear of Ashi) has not been completed!
