Book of Hours - Explain it Like I’m Five

I’m in love with this game. Truly has everything I love in it and then some.

But I wish I could better understand the lore, the setting, everything a little bit better because it’s kind of a bit too much for my little brain.

So, please ELIF: what’s the lore behind hush house? who are the dewulfs and what do they do? Please explain to me your favorite bit of lore!!
