Source
Source is the name the Slylandro have for their homeworld Beta Corvi IV. It is the only known Gas Giant that has evolved life on it. Many species live on Source and one has even gained sentience: the Slylandro.
The Slylandro divide Source into three distinct regions: their world, the Depths, and Void. Their world consists of the 500 kilometer band of atmosphere where the Slylandro can survive with ease. Beneath their world lies the Depths where conditions become increasingly dark and hostile the deeper one goes. Traversing into the Depths leaves long-lasting tissue scars on or even ruptures the Slylandros' gas bags. Any large scale constructions of tools or weapons are eventually dragged into the Depths by their own weight. Void lies above their world. Slylandro become giddy and behave inappropriately in the rarefied atmosphere of Void.
Source's rotation period is also the basis the Slylandro Timekeeping system.
