Welcome my brother. I hope you have come to collect Veren's pendant of Water.
You have come a long way to get to this point, and once we collect all pendants, we will be able to open the tomb and get the four rune stones.
As you know, you must begin by finding the Altar of Water, and placing your hand upon it. This will awaken the first circle of guardians.
Return to me once you have done this.
