In the formation of his Class, the Primordial Record understood that the nine Supreme Circles created by Rowan were excluded, and so it focused on the nine that were not.
Maybe it was because of the intense damage they suffered, but when the Primordial Record reached out for the Supreme Circle, their struggles were not as intense as Rowan would have thought, and it did not take long for them to break.
The first Circle selected by the Primordial Record was the ninth, perhaps it was because it was the strongest and the Singularity needed fuel for it to create his Class, but the Primordial Record did not start from the least, but from the greatest.
