Neró Ocean, the ocean of Water.

The name seems to give away what this country is all about. Once, it was a beautiful, thriving city. Though some time ago, the entire city was flooded. Due to this, many died, and lost all their belongings. The survivors were forced to find other places to live, but there was those who decided to adapt to the situation. As such, they built their houses, stores, and many other various buildings upon giant, floating rafts, which they anchored to the seafloor below. The only way to get from raft to raft is by swimming or by boat. Though it does seem to be rather devoid of monster life, allowing for safe swimming.
