Sunken Journal from Umbra, a Mystery of the Shrine of Ancient Tears.
I thought I knew all there was to know about the merfolk, but after visiting the Shrine I felt like I was missing something. A part of their story that might explain this strange place. So I asked around. That's when tales of ships being dragged below by creatures that looked like merfolk started to surface. I couldn't believe my ears, the merfolk wouldn't act this way. What on the seas could be happening? I spoke to every pirate who knew anything and they all told the same tale: a terrible scratching on their hulls and the sound of a sad voice on the wind.
