Vel is more of an adventurer than I am, but she still gets a little nervous traveling in underwater areas. Vashj'ir was one of these zones that definitely made me uneasy. Lots of sea creatures, random elites swimming around, and the fact that you can't see much ahead of you regardless how high you turn your view distance up.
|Note: If you plan on going see these skeletons, you will die from Fatigue. When you will release you will be ported to the the Barrens and be forced to accept a Spirit Resurrection.|

There are two quest lines in Vashj'ir involving Nespirah and L'ghorek who are labeled as "ancient ones" or Demi Gods in the Warcraft universe. Sadly, L'ghorek passes from irreversible damage caused by the Twilight Cult, but Nespirah is able to be saved. The Naga are using slaves inside of her to mine pearls. The pearls are mentioned in a quest given by Wavespeaker Tulra, but they aren't elaborated on any further after you turn it in.

Another is in the Dread Wastes. You will find Gokk'lok, this huge ancient clam. After defeating him, the pearl inside him will magically float towards Rikkitun Village, and you will get a quest to return to the chieftain. He will give you Gokk'lok's Shell as a reward, and around the village you can see the little sprites worshiping the pearl.
|All praise the pearl!|
