Thre'Fassan was the homeworld of the Shrin'Yar in their home galaxy of M-101. It was destroyed at the beginning of the Century of Blood; the great civil war that marked the end of the Shrin'Yar rule of M-101.
Thre'Fassan was home to the Shrin'Yar species for many hundreds of years before the Altera first began to travel amongst the stars.
