Tablet of Vision:
Suddenly, huge amounts of knowledge are painfully seared into your brain. The cascade of brief images is unintelligible at first...
But then, the next tablet comes into view! It looks to be located in the area northeast of the Ketra Orc Outpost! It's surrounded by golems! One of those filthy creatures has the Stone of Commune! And then the vision fades...
The tablet goes still and dark, as if nothing had happened. Now go to the northeast of the Ketra Orc Outpost and get the Stone of Commune.
