Rose Adelaire.
Among Damien's wives, her origin was the least impressive.
She was a princess of a great Empire on Apeiron, sure, but that was the extent of it. The number of people in similar positions to her across the universe was in the millions, if not more.
Her affinities also weren't anything to brag about.
A wind affinity and an illusion affinity, while the latter was definitely rare, it wasn't all that special, at least not in the way it was usually perceived.
Because at the end of the day, illusions were just illusions. Higher caliber experts could see through them all with their perception abilities no matter what kind of strength was poured into them.
Elena was from Earth, but her origins were mysterious and connected to a race long extinct from Grand Heavens Boundary. As for Ruyue, while she also had common origins in the grand scheme of things, she was blessed with an absolute Yin affinity that destined her for greatness.
