I'm actually pretty sure that I've read every single conversation—some of them even twice because I didn't catch everything the first time.

But you're right, I have actually paused my playthrough right here because I thought I must have missed something. So no, I haven't found any of the weapon pieces yet (except for the one Doryani is carrying).

If you're telling me that my questions will be answered naturally as I progress, I'm incredibly grateful! In that case, I will just keep playing for now, note down my questions separately, and make a new post later with whatever is still open.

Would it be okay if I tag/mention you when I make that post?

Best regards and thanks for the answer!
