CAMRON'S FAMILIARITY
From another person's perspective, Camron's, the Dark Brigadier General looked familiar, not in the sense that he knew the Dark Being but rather, he had seen a Dark Being with similar features.
He saw Dark Beings of similar attributes in the vision that he was shown by the artifact that they took in Eddon. Although then he saw millions and millions of such species, some of them stood out from the rest, as this one that he saw watching Alex, looked similar.
The difference between this one here and the one that he saw in the vision is their cultivation levels and aura. Camron could tell that there is a huge difference between the QI that he experienced in that vision and the one that is present in the 3 Plain Realms.
The QI in the 3 Plain Realms lacks the chaotic power that it needs as if it had been filtered out before permitting the 3 Plain Realms.
