Priest Cain:
While you were gone I did some research, by the by, and I believe the Contractor deaths have something to do with the Seven Signs.
As I'm sure you know, the forces of dawn wage war with the forces of dusk for control over the three Seals. I may as well tell you now; I belong to the Order of the Dawn. That's actually how I came to be in charge of this place.
You've had first-hand experiences of these murders, as well as the murderers, and I feel I would be remiss in not extending our hand to you. Help us, and we will reward you well.
"I'll help you, certainly."
