The Test of Night was the second in a series of trials that the Nightbrothers and Nightsisters of Dathomir were forced to pass to go on to become full warriors. Candidates fought much like they did in the Test of Fury, save for lacking the light of Dathomir's four moons. Fighters sometimes employed the technique known as the Ears of the Chiroptix to pass the trial. Only Savage Opress and Feral passed the Test of Night during Asajj Ventress's Selection.
