I was wandering in the Alik'r Desert in ESO, when I suddenly found a totally random NPC called "Hayazzin" , who gave me a rather strange quest. He kept mentioning Sounds, and a "Pearl". A option came up to ask him about this, and he suddenly told me the Redguard creation myth, but he kept mentioning this rather strange Pearl. I made screenshots of the conversation with him:

When you ask him "What happens after the call is answered?", he repeats the whole conversation.

In his quest, you had to bring a goat to a small island in a pond, and had to feed it to a Giant Snake. The Giant Snake most likely symbolizes Sep.

So, what the hell could that "Pearl" Hayazzin keeps mentioning be?
