The name of the species we are talking about is Rumbi, sing. Rumbos. The name of their home planet as well as the name of their home solar system are unfortunately lost in time. Much is unknown to us about it even though we are able to observe it from Earth. When we point our instruments towards their solar system we see it the way it was 75 000 years ago. Back then they still inhabited their home, but as of now their home does not exist anymore, their star has exploded in a violent supernova. But we have a lot to discuss till we get there.
Home solar system of the Rumbi. In the middle is a star and a black hole that orbit around each other. Their home planet is the second furthest away from the center.
