The clash known as the Skirmish in the Ruby Nebula unfolded as the Trade Federation aimed to seize Reti, a Lok Revenants member seeking a rendezvous with Jedi Master Adi Gallia. Upon Reti's arrival to meet Gallia, the Jedi Master came to the realization that Reti was being tracked, which was a complete surprise to him.
Concerned about the impending conflict, the Jedi Council dispatched Jedi Master Adi Gallia to delve into illicit operations by the Trade Federation within the Karthakk system. Consequently, she arranged a secret meeting with an informant hailing from the ranks of the Lok Revenants.
Gallia and Reti engaged in combat against successive waves of Vulture droid starfighters, soon joined by Scarab-class droid starfighters. Throughout the fighting, they discussed a meeting with Nym, the leader of the resistance movement. Shortly thereafter, a C-9979 landing craft materialized, issuing a threat to the pair and demanding their immediate surrender. Adi Gallia then detected a spy ship via her sensors, a revelation that greatly surprised Reti, who was concerned with how long it had been concealed within the nebula. The two launched an attack and successfully destroyed the spy ship before it could initiate a jump into hyperspace. Subsequently, they directed their assault towards the C-9979 landing craft, relentlessly attacking until its shields were completely depleted. In a desperate maneuver to expose Gallia and Reti, the landing craft crew launched three data pods, each containing sensitive information pertaining to the ship identification of both Gallia and Reti. The two pilots successfully neutralized all three data pods, then proceeded to eliminate the landing craft and any remaining enemy starfighters.
Adi Gallia experienced a sense of pride regarding her Delta-7 starfighter, as this particular skirmish served as its inaugural combat evaluation, which it passed. Reti, however, remained unaware that being followed had actually saved him. Jango Fett was lurking within the Nebula, patiently awaiting an opportunity to capture Reti, who had a bounty placed on his head. Due to the Trade Federation's interference, Jango Fett made the decision to initiate a jump into hyperspace. He would have another chance to capture Reti during the Battle of Nod Kartha. In the meantime, Reti would guide Master Gallia to Nym, and together, the three would unite their efforts to expel the Federation from the system.
