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, taking place between 1147 and 1230 SSD. Following the Rathyn cataclysm of 1147, it became clear that the stellar conflagrations triggered by the collapse of the ley-lines would destroy all life on the worlds of the inner galactic core, while increasing cost and difficulty of faster-than-light travel over the following decade made an FtL evacuation of the entire population of the core infeasible. While a substantial number of people fled rimwards in faster than light ships, the majority of the core's population relocated to fleets of slower-than-light generation ships constructed by authorities under the Unified Evacuation Plan. Due to the constraints on trajectory imposed by the supernovae, most ships were forced to flee away from colonized space in the East, although a handful of vessels were able to make their way eastward; almost all artifacts of the pre-Silence inner core, as well as all surviving records of pre-contact Kasatha civilization, are found aboard (or in the colonies established from) the known ships launched during the Evacuation of Kasath.

Background

Although largely spared from the bloody conflict of the Ley Wars, the damage dealt to the ley-lines caused substantial disruptions to travel and trade in the inner core in the form of frequent and intense star-storms.
