- "I warn you. The men are easy to acquire, hard to control."
- ―Mother Talzin
The Nightbrothers were a tribal group of Dathomirian Zabrak males who lived in a village on the far side of the planet Dathomir. They lived in subservience to the Dathomirian Nightsisters. The infamous Darth Maul, apprentice to the Dark Lord of the Sith Darth Sidious, was born a nightbrother. They were all Force-sensitive.
During the Clone Wars, Nightsister and Count Dooku's former assassin, Asajj Ventress, came to the village to choose one of the heads of the tribe to serve her. Ventress then arranged for three tests to see their potential. During the third and final test, Ventress fought Savage Opress and his brother Feral. After Feral was defeated, Savage continued to fight Ventress but lost to her becoming her servant. Following the Devaron massacre, the Nightbrothers fought Jedi Knights Obi-Wan Kenobi and Anakin Skywalker, but yielded when Skywalker subdued Brother Viscus. Viscus then told them that Opress had been taken by one of Talzin's Nightsisters as a mate. As the Jedi left, Viscus ordered the Nightbrothers to let them go.
Unlike the Nightsisters the Nightbrothers were spared the wrath of the Separatists during the Battle of Dathomir, and were sent by Talzin to Maul's aid in her stead when he requested her help. Viscus and his fellow Zabraks engaged Dooku in combat, but were swiftly defeated by the Sith Lord. Dooku would then be captured by the Shadow Collective before he had the chance to kill Viscus. Later, after Dooku feigned allegiance to Maul, the latter brought him to the Nightbrother village on Dathomir where Viscus awaited, and Viscus escorted them to the heart of Mother Talzin's power where the Great Mother possessed Dooku's body to drain his energy. Viscus and the Nightbrothers then left to prepare Talzin's chambers. Soon thereafter the village came under attack by the Confederacy, with only Maul escaping.
