Dajh Katzroy is a minor character in Final Fantasy XIII and Final Fantasy XIII-2. He is the son of Sazh Katzroy and the motivation for Sazh's actions in both games. Losing his mother three years before the events of the first game, Sazh has taken care of him as a single parent.
In Final Fantasy XIII, Sazh, after being begged to, took Dajh to see the dormant Cocoon fal'Cie at the Euride Gorge power plant. While off buying a Chocobo Chick for Dajh, Dajh wandered off and accidently became a Sanctum l'Cie. Dajh was taken into custody by the Sanctum, who desired to use his power of sensing Pulse fal'Cie. Believing his son's focus was to destroy the Bodhum Pulse fal'Cie, Sazh headed for the Pulse Vestige, where he met the rest of the group and became a Pulse l'Cie.
