Bathyos is a pelagic planet, meaning more than 90% of its surface is covered by water. Most of the inhabitants are sentient fish who live in cities made of coral.
The Bathyosians are mostly sentient water-dwelling beings. Some are highly anthropomorphized (with heads and hands) while others are closer in appearance to fish.
- Bathyos is derived from the Greek word "bathos", which translates to "depth". It is commonly used to refer to ocean depths. However, one might mistake the name as referring to a bath or bathtub.
