A devastating massacre transpired on the planet Orto Norwe, specifically in Yellowblade's Landing, during the period known as the Clone Wars.
Following the successful escape of both Obi-Wan Kenobi and Asajj Ventress during the Skirmish above Raydonia, Darth Maul and Savage Opress touched down on Orto Norwe with the intention of establishing a new army. Upon entering a local cantina located in Yellowblade's Landing, they initiated a search for the individual in charge of the local rally outpost. The bartender directed Maul's attention to Nukss, the leader of the local gang, The Scourge. Nukss presented Maul and Savage with an ultimatum: either join his gang or pay them protection money. Maul responded with a counter-threat: either join them, or die.
As the conflict erupted, Maul and Savage swiftly eliminated the six gang members, leaving Nukss defenseless before Maul. Nukss pleaded to be allowed to serve the Zabraks, but Maul, deeming him useless, decided to execute him. Savage, however, opted to spare one member, intending for them to spread word and draw the Jedi to their location. Maul vehemently opposed this plan, arguing that they were not yet prepared for an encounter with the Jedi and should remain hidden. To ensure their secrecy, Maul insisted on eliminating all witnesses, which meant slaughtering everyone present within the cantina at the time of the battle.
News of the Sith duo's arrival at Yellowblade's Landing quickly spread to the Coruscant underworld, where Plo Koon received intelligence from his informants confirming their location. Two rotations later, Plo Koon, accompanied by Obi-Wan Kenobi, Bruu Jun-Fan and his Padawan Tatsu, and Master Grohto, arrived on the frozen planet. There, they discovered a Turtle Tanker and the bodies of those massacred within the cantina.
