ThonBoka Nebula

The ThonBoka Nebula is a sack-shaped nebula that is full of gases, organic molecules, carapace creatures and interstellar plankton. It is also home to the sentient Oswaft species, a manta-ray like creature that feeds on the nutrients inside the Nebula.

The nebula can only be entered from one side and contains three blue-white stars in the center region, that surround the only architectural structure in the nebula, the Cave of Elders. This cave is made entirely of precious gemstones processed by the Oswaft, and is a scale model of the nebula.
