Egurgadi is a world totally covered with water. Though the water at the poles is cold, it rarely freezes due to there being nothing to prevent the mixing of warmer waters. Apart from a few research scientists, the world is unpopulated by humans.

The population of Egurgadi is officially in the hundreds, but the actual population of sophonts is in the millions, they just aren't recognised as such. Living in the seas, large whale-like creatures popularly known as 'cat-fish' due to their long whiskers form an intelligent society. They have no technological civilisation, but they have language, philosophy and poetry.
