During her childhood, Kensa befriended Bayek and taught him the ways of her tribe, hunting and trapping. Eventually, Kensa’s tribe had to move on. Several years later in 70 BCE, Kensa met up with Bayek, Aya, and the street urchin Tuta in Thebes while Bayek was searching for his missing father, Sabu. They learned that Menna, a grave robber who had attacked Bayek’s home years earlier, was also in Thebes. With Seri and Neka, two of Kensa’s family, the quartet hunted for Menna.
Catching up with Bayek, Kensa helped him gain access to the arena, where they formed a team alternately called The Guardians of Siwa or The Siwan Warriors. Together, Kensa and Bayek fought and climbed the ranks to challenge the arena champions, the Gallic brothers Diovicos and Viridovix. After defeating them, Kensa learned of Bayek’s true motives for entering the arena; Bayek believed them to be responsible for Shadya’s death. Kensa offered to help him, though Bayek refused and left the arena.
