There was a hierarchy when it came to the ultimate elements.
According to the information that both Angakok and the Primal God Of War had left behind, the tier7 promotion grounds were located just beyond the universe after the barrier of space, time and gravity that seperated the controlled universe from the celestial realm.
Only those at the peak of tier6 were allowed to pass the barrier and appear in the realm of ' Chaotic Energies ' once every 500 years for a chance to advance to tier7.
First hand experiences of both Angakok and the Primal God depicted the journey to becoming tier7 as if being watched continuously by superior beings that were looking down on a kid learning to wield a weapon for the first time ever.
Although the Primal God Of War was not sure— he believed that the realm of Chaotic Energies was created because of the clash between two celestials, leaving an unstable plane of ultimate energies in the aftermath.
