...is a Uranus-sized gas giant at about 50,000 km in diameter – about 175,000,000 km out from Stera in the outer bounds of Stera’s habitable zone. It’s mainly known for the city of Orche, a unique city that floats in the stratosphere of Cellis.
Orche was founded by many people wanting to escape much of modern technology, and as such, Orche contains a very large population of "naturalists", people who refrain from much of modern technology. Other than electronic instruments, nearly every electronic is *heavily* frowned upon.
The largest monuments in Orche are the Windows of Clef, a set of 3 windows representing the Bass, Alto and Treble clefs in historic sheet music, looking at the clouds beneath.
Its two moons are most often used for parking or storage, partially for Cellis, although some interstellar freighters use it as a stop.
