Biography
During the First Contact War, Buca came to serve the pack belonging to Chieftain Jovus as his second-in-command.

After the end of the war, Jovus had to resort to raiding both ex-Covenant and human territories for resources. After assaulting the human outpost Braden Station, Jovus had Buca present him to the commanding officer of the station, as Buca was fluent in English. However, the soldier was frightened by thinking Jovus was Atriox, which deeply enraged the old Chieftain, who proceeded to kill the human and lead his pack into destroying and salvaging all they could in the facility. When Jovus questioned why Atriox gained such a reputation, Buca went to explain his feats after the fall of the Covenant, which interested Jovus, that ordered his soldiers to track down Atriox.

The pack was able to track the Banished to the former Covenant colony Karava, where they were notified Atriox awaited them by both Decimus and Let 'Volir, Atriox' right hand men. When they were dispatched to the planet, a clash ensued, until Atriox himself appeared. Atriox revealed he did not want a fight, and was actually hoping that Jovus and his pack would join his side as there were many within the pack who contacted Atriox. As soon as Jovus asked who did it, Buca revealed that, while Jovus was a great warrior, he was lusting for destruction instead of stability, revealing himself as the mole. Instead of attempting to form an alliance, Jovus attempted to kill Atriox, who killed him by smashing his skull with the Chainbreaker. Buca later wondered why Jovus fought back, despite knowing he would not survive, leading Atriox to tell that Jovus didn't want to be spared, and wanted to prove himself more worthy by killing him.
