Tidros

Tidros was the capital city of the planet Champala, homeworld of the sentient Chagrian species. Like all Chagrian settlements, it was built within a tidal zone of one of the planet's oceans, meaning it was regularly entirely submerged by rising tides. The only part of the city designed to remain above water at all times was its spaceport.
