The Vermillion raid was a venture executed by T'onga's crew, a group of individuals working for the bounty hunter T'onga, in 3 ABY. Their objective was to liberate Cadeliah from Crimson Dawn, as she was being held captive. Cadeliah is the successor to both the Unbroken Clan and the Mourner's Wail Syndicate. To locate the Dawn's flagship, the Vermillion, where Cadeliah was a prisoner, the crew enlisted the help of bounty hunter Dengar. However, unbeknownst to them, Dengar was secretly allied with Crimson Dawn and had infiltrated their ranks to lure them into a carefully laid trap. Dengar guided the crew to Nal Hutta, where the Vermillion had journeyed to meet with its operatives. Following Dengar's diversion, the crew managed to board the vessel. Dengar then told T'onga and her team that Cadeliah was located in the brig, directing them to a turbolift before departing.
While ascending in the lift, the crew began to suspect Dengar's deception and were subsequently ambushed by Crimson Dawn soldiers upon exiting. Despite this, they managed to overcome their attackers. After defeating the soldiers, the Knights of Ren, Force-users of the dark side and allies of Crimson Dawn, appeared with the intention of eliminating the crew.
