Evacuation of Kasath

The evacuation of Kasath, known as the Great Flight in Kasatha histories, was one of the largest exoduses in the history of Elyrion. Over the 11 years between the Rathyn cataclysm and the second nova of the Beacon, more than three billion Kasatha - half the planet's pre-Silence population - fled their homeworld, either on small faster-than-light ships to the colonies of inner Aenaz or on vast slower-than-light generation ships intended to permanently relocate the cultural, historic, political, and biological heritage of Kasath to worlds hundreds of light-years rimward. Although the evacuation did save much of Kasatha civilization, it was not able to relocate approximately three and a half billion souls, who perished in the supernova of 1159.
