- "I have come for the Selection."
"Yes, yes, of course. Line up! Heads of each tribe, line up for the sister!"
- ―Asajj Ventress and Brother Viscus
The Selection was a three-ritual series of brutal trials in which the Nightsisters of Dathomir chose men from the Nightbrother clan to serve as their mates and servants. While the Selection was only for Nightbrothers, the three trials of the Selection were also employed to select Nightsisters ready for full warrior status.
The ceremony consisted of the Test of Fury, the Test of Night, and the Test of Elevation. All three trials were held at the arena on Dathomir known as the Crucible. It was through this method that Asajj Ventress handpicked Savage Opress to become her agent in a plot against her former master, Count Dooku.
