Kuroga

Kuroga is an enormous gas giant with a ring system. It contains more than 100 moons, the largest of which is the oceanic world Azima. Kuroga has large clouds of ammonia, and appears orange.

Physical characteristics
The atmosphere contains microbes which dwell within the ammonia clouds. It is believed that life on Azima originated from extremophiles from Kuroga.

The moon Azima is also tidally heated by Kuroga, which keeps the moon at a stable, constant temperature.
