High Priest Gereth:
The way to the grail...
I think I can guide you there. The moment I was born, and the moment I became a priest of Sayha, Sayha taught me a single line of prayer...that prayer will certainly lead you to your destination.
Now. You should go. I will find Kain Van Halter and tell him where you went. I will send you to the Chamber of Prophecies.
Go to the Chamber of Prophecies
