Great Collapse

The Great Collapse, also known as the Kathol Rift Disaster, was an event where one of two ancient Kathol Launch Gates were detonated by a marauding Dark Jedi, over one thousand years before the Battle of Yavin IV.

As a result of the explosion which rippled through both hyperspace and realspace, a transdimensional tear in space-time "flipped" a portion of the Charr Ontee populace into the parallel galactic realm of Otherspace, stranding them where they ultimately evolved into the Charon. The location of the Great Collapse was within orbit of the world of Kathol, and served as the focal point for a second event horizon that penetrated between realspace and Otherspace, known as the Aperture.
