Grand Master Samael:
Welcome back! Tell me, what have you learned?
The forbidden knowledge is truly passed on to the one who holds the Stone of Commune.
Good job! But, why did you come back?
The Stone of Commune? You mean this? Actually, there were several fragments attached to the tablet. I gave you the analyzed one. This may be the one that you're looking for now. Unfortunately, it's incomplete. You must find another fragment! In fact, I know where the fragment is, but haven't been able to get it yet, as it will be quite difficult. Will you get it for me?
"What do I need to do?"
