The Fisher King's tomb-- the guy who's the whole reason the Land of Rot exists. His corpse is cursed. I didn't touch it, but I did take a painting with me. Which isn't cursed, don't worry -- we checked it once we found it.

[Or if it is, it's impossible to detect through the means of an average mage, but he hasn't experienced any adverse effects so far if that's the case.]

I'm going to go to the Archivists' to research it, so you're welcome to come with me if you enjoy doing homework? [And because he doesn't want Lorenz to feel like he doesn't trust him with this, after not inviting him along before.] Could be useful to know if the person in the painting is anyone significant.
