High Priestess Levian:
From all accounts it seems that the lizardmen worship Bifrons as a god. I would not be surprised to discover that he was being controlled by an even higher being.
I sense a great evil on the south shore of Gludio. You will not be able to deal with this menace alone, you must bring your trusted comrades with you.
You must kill the evil spirit and find a weird looking chest. Inside this chest you will find the mark of darkness. Bring it to me. Then, together, with the power of the goddess, we will destroy that blasphemous object.
