So is a player that helps build a spam building after it is placed by another player considered guilty?

Quest completed! Thank you.

I took the three books to the monk near the library. Now I have the symbol of LI-NIR MUEN and the book Age of the high priests but when I try to talk to Sebastious, there is no question mark above his head.

What am I missing?

Thank you all for your help.
