The Ones

The Ones were a family of exceptionally powerful Force wielders who lived in the ethereal realm of Mortis during the Clone Wars. They moved to Mortis after exiling the dark side entity Abeloth—known to the Thuruht Killiks, client species of the Celestials, as the "Bringer of Chaos"—on their home planet. The Ones consisted of the Son and the Daughter, who were respectively embodiments of the dark and light sides of the Force, and the Father, Keeper of the Balance. According to Thuruht, the Ones were direct manifestations of the Celestials.

In the Nightsisters' religion, the Son and the Daughter were worshiped as the Twin Deities.
