Vaka 'Kulul was a Sangheili who served the Wartorn as an Ossoona and had infiltrated the Arbiter's Swords of Sanghelios. After years of gathering intelligence on the Arbiter's faction, 'Kulul was killed by friendly fire from an by accident.

Covenant service
During the war against humanity, Vaka 'Kulul was tasked with the discovery of human colonies by bartering with human rebels. 'Kulul can be tied to the discovery of Actium and Camber and the assassination of several UEG diplomats attempting to forge an alliance with rebel factions.

Spy pun
After the Great Schism, 'Kulul entered the service of the Wartorn as an independent contractor. On November 19, 2553, the Sangheili had successfully infiltrated the Swords of Sanghelios after silencing a fellow recruit who recognized him. Climbing the ranks and gaining prestige, Vaka 'Kulul had gained access to a number of data files belonging to the SoS including but not limited to information about the Shadow of Intent, allied colonies, and troop numbers which he had sent to his employers.

Vaka 'Kulul was present at the Arbiter's encampment when Fireteam Osiris had arrived in order to gain access to the Sanghelios Guardian, he stood guard at the entrance of the camp itself as they passed. Although he was not present during the Battle of Nuusra, he participated in the attack on Sunaion when he had killed a Storm Sangheili and took his place, claiming his victim was injured and couldn't join the assault. During the attack, his squad was tasked with securing an elevator used by the Spartan fireteam. 'Kulul would abandon his squad after coming under attack and follow the Spartan-IVs, recording what they did and how well they performed as well as information about the Guardian, Prometheans, and Genesis.

Because of the sheer amount of intelligence he had gathered in very little time, Vaka 'Kulul was awarded with a substantial increase in his reward but chose to continue his work in the SoS as he felt events were beginning to get interesting.

Death
Vaka 'Kulul would meet his demise when a Promethean incursion made its way deep within SoS territory on Sanghelios two months after Sunaion and the defeat of the Covenant. When his squad attempted to push the Forerunner constructs back, an Unggoy assigned to him misfired a charged plasma bolt into an incoming Banshee which would crash into the ground and splatter Vaka 'Kulul across several feet.
