Whispering Abyss

Whispering Abyss is the sea around Navavia that is inhabited by Merpeople. It's very deep water and the Merpeople don't usually go near the surface, the only time they ever did was when they sensed that the 120 slaves had entered the water and they wanted to experiment on them. The area that is now Navavia used to belong to Whispering Abyss, until the Elves made the geysir erupt which created Navavia. The Merpeople have been desperately trying to get back the area, through both peaceful approaches and through wars such as the First Merfolk War.

Etymology
Whispering Abyss was given its name by the Elves. It was named after the merpeoples' language that sounds like a mixture between hissing, scratching and whispering.
