Water Castle:
A castle that now seems only like a mere village, in the last fifty years the
castle that was there was sunken into the sea from a massive title wave. The village used to be
just along the outskirts, part of the top of the wall of the sunken city is still above water and visible
from the village, the people know a secret about the waters and have magic items which allows them to go
under the water for long periods of time. The area has many tropical foods and is semi exotic.
The government is run from inside the suken cities walls by Merfolk, sprites and sea elves.
But in exchange from the humans they get plenty of fish and underwater creatures for foods to eat and live off of,
there is also plenty of old and bizzare treasures that wash along shore during high tide and are collected by the
kids of the region. The guardians to the secret of the sunken castle are mages who spend most of thier time in the sunken
city. The cities guards are all human until you reach the underwater levels, in the underwater levels the guards are mainly
Merfolk.(Most of the population is Merfolk, sea elves, sprites, humans and a few nymphs)

Most likely a merfolk or a sea elf for a ruler here
