Din Nebula
this vast area of interstellar gases was located in the Moddell Sector of the galaxy, in the rough triangle formed by the planets Endor, Trindello, and Zorbia. It was known to the Ewoks as the Gorax King's Heart, and contained the Din Pulsar as well as a planet-sized diamond that was believed to have once been the core of a gas giant. During the supernova that created the Din Pulsar, the violent explosion apparently stripped a huge gas giant of all its atmosphere, exposing the diamond. This diamond created a huge mass shadow in hyperspace, making travel through the Din Nebula impossible.
