Rivon is a moon orbiting a water giant in the Centauri system.

Habitability

Rivon is covered in a liquid water ocean, which was unfrozen after several trillion tons of CO₂ were sent into the atmosphere when it experienced incredible tidal stresses after being captured by its host planet, 1 billion years ago. 18 million years after the oceans became liquid, life began to develop, resulting in a bacteria much like blue green algae to evolve after 500 million years. this bacteria slowly turned its atmosphere of CO₂, into a breathable one.

Colonization Attempts

A space faring species known as the Delions has plans to colonize Rivon, the Delions are the only species within more than a parsec that doesn't find Helium toxic, and due to this fact they are the only ones with plans to colonize it.
