Zeraphine was a daughter of a Prime. And this was inconceivable considering that Primes was no longer considered to be humans. They were an altogether different kind of being. Mortal humans couldn't conceive what these beings are. And for such a being to give birth to a child was all the more impossible.
During the transformation between a Principal and a Prime, their bodies transform and become beings that didn't have gender. As beings that exist and can interact beyond the three-dimension, they have changed and cannot even be described to be beings who have locality in time and space.
The transformation is so different that these beings act and think differently. To Principals and Presiders, Primes were strange, enigmatic beings.
And among all Primes, Prime Zephirus was the strangest one of all.
