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?

Lorkhan's Heart, I'm assuming. The second screen mentions the "Pearl" fell out of Sep's pocket. It goes back to this:

It mentions that Sep put a star into his pocket, which then fell out after Tall Papa squashed him and became the Pearl, not that it fell out of his mouth.

Oh sorry, I just saw my error.

Its the same story, just phrased a little different.

The 4th picture seems to be referring to the Psijic Endeavor, so yes, the pearl is most likely Lorkhan's Heart.

Actually, I found something connected to that Pearl.

There's a quest called "Tharayya's Trail", in which you have to follow a Dwemer researcher into several Dwemer ruins. That Dwemer researcher is searching for an artifact called the "Guardian's Eye".

Anyways, the thing is that I have the Skyshard Addon installed (shows all Skyshards on the map), and in the second Dwemer ruin of the quest, it shows that there's a Skyshard in the dungeon. The description of its location is also given (since Skyshards were supposed to be found by reading these descriptions and figuring the location of it out): "Second stop on her search for the Pearl."

That Dwemer researcher is searching for an artifact called the "Guardian's Eye", but that description mentions a Pearl, instead of that Eye. Could the Pearl actually refer to that artifact?

(Didn't complete the quest yet, I don't know what that artifact really is.)

There may be more than one oyster.
