Bring the Corrupted Seal of Erudition to Arbiter Takij.
It does not take a scholar to sense the corrupted power this seal contains.
It would be wise to bring it to the authorities.
I sense you have made a grave discovery, but you have nothing to show for it. What have you found?
You found the seal? That was why I was sent here, friend - to find this seal and destroy it.
I was told nothing more, and so, there is nothing more I can tell you, except that I have spent weeks searching for that seal... and you simply stumble upon it.
If this were gold or silver, I would say you were blessed by the gods, but this is an item of great evil. Stumbling upon evil such as this is no blessing.
