Legacy of the Force
At some point before 30 ABY, a Sith known as Darth Krayt founded the One Sith or the New Sith Order on Korriban, the ancient Sith burial world. In this new Sith cult, most of the followers were trained from birth, sported a red-and-black tattooed appearance and carried lightsabers with a yorik coral-styled hilt design. This Sith Order was considered heretical by the holocrons of Darth Andeddu and Darth Bane. By the year 130 ABY, the One Sith had risen to take the place of Lumiya’s Sith faction, itself the remnant of Darth Bane’s Order.
