Black hole at Sebbadon

The Black Hole of Sebbadon was the barycentre of the remote Sebbadon system, located many thousands of light years above the Galactic plane. The system was so remote that from it the entire galaxy was visible.

Sebbadon was the site of an intense struggle (the Battle of Sebbadon) between the Old Republic forces, the Sith Empire, and a horde of tens of thousands of Hex-droids, the remarkable brainchild of the refugee Lema Xandret.

The black hole was orbited by the planet Sebbadon, which was the site where much of the Battle of Sebbadon took place. Due to the black hole's intense gravity, the planet's core was rocked by tidal forces, making it incredibly volcanic.

The black hole itself claimed the lives of many of both sides of the battle, swallowing entire starships whole. It is rumoured that, a few weeks after the battle of Sebbadon, the black hole finally claimed the planet itself, and all what was left of Lema Xandret's legacy was sucked into oblivion.

Size and Mass
The black hole of Sebbadon was of stellar mass, about 15 times the mass of a common yellow dwarf star. It was created in a hypernova explosion and gamma ray burst some 2000 years before its discovery by Lema Xandret (the records of this event can still be found in some ancient cultures). The planet Sebbadon lay relatively close to the black hole prior to its destruction inside it, and was geologically very young. It is believed that the planet was formed in the shockwave of the explosion which created the black hole, and migrated quickly inward. Despite producing incredible amounts of energy, the hypernova did not leave a large nebula in its wake, a most of the gas was sucked in by the black hole.
