Second migration (SWA)

The second migration was an event that occurred roughly a after the Tho Yor Awakening, in which all non- individuals living on the   Tython were ordered to leave the planet for their own safety.

As a result of their departure, a majority of the planets and s in the Tythos system were settled by the departees and by the Dai Bendu, who also elected to leave Tython despite being Force-sensitive, as they believed that the Je'daii Order was straying too far from the Dai Bendu's own ideals. Those Dai Bendu monks then formed the Kali Bendu, on the planet Kalimahr.

All of the terrestrial planets in the were settled in one way or another by the former Tythans, as well as a number of major moons of the system, including Tython's moons Ashla and Bogan.
