Eos had created this weapon in secret, and Eva was the only Primordial inside the Origin Realm that could use this weapon. This weapon gave Eva access to hundreds of his Archai, and these were one of his most powerful creations because they were a part of his body.
One of the biggest weakness for Primordials were not their Origin Essence or Force, in fact, every New Primordial were uniquely powerful, and Eos believed that every of the New Primordials he had created could match the Ancient Primordials or even their hidden enemies, the Luminious, however, the weakness they faced was power.
Even as an eighth-dimensional Old One, Eos could crush any Primordial, and one of the reasons he could do this was the weight of his existence and the raw power that his impossibly massive foundation could emit.
