You found something, didn't you? Well, don't keep me waiting in suspense. Let's see it.
Hmmm... Given the contents of this encyclical, I believe you have just made the acquaintance of the real Inquisitor Guillaime.
Newly come to Coerthas and murdered on the day of his arrival... Yes, it would have been a simple thing to assume his identity, for even if he were to behave oddly, who would dare question the wisdom of a papal appointment?
Still, while this is incontrovertible proof that the inquisitor is an impostor, we have yet to discern his true identity, or why he has decided to oppose us.
We must proceed quickly,
Forename, before he learns that his deception has been discovered!
