With the final words of Theta, the other aliens honed their skills to fight, for they were powerful but not as skillful. They were more suited to be the scientists and farmers of their coalition of the races they were in, and the Rek'Nee were more like the enforcers between the races. The other two races controlled politics between the other four races before reporting to the king. The kings' race is unknown to anyone as their history referred to them as angels or beings of light.
As time went on for the Naki to try and build their power, they could conjure energy provided by the universe and unlock abilities that were innately within them, allowing them to more confidently feel like they could take on the Rek'Nee or the King's army. Theta then proceeded with their experiments with their DNA to create a perfect match.
