Grand Magister Arkenias:
I didn't scare you off, huh? Well, I won't try to stop you.
Just one more thing... The Tablet of Vision can't be read alone. Only by using the Stone of Commune can you decipher it. The Stone of Commune acts as a medium, and you absorb the information directly into your body! This is known as communing with the stone tablet. At one time Stones of Commune were quite rare, but they've been turning up in lots of places lately! I fear that there are unseen, foreign hands at work here...
You should go and talk to Magister Alminas in Goddard Castle Town. He'll know best what you should do next... Take a copy of the guild bulletin with you!
