It seems like the race is considered fairly weak?
Ig they’re like omega core. Because they’re pretty but weak so they get used or disliked
They're a relatively weak race which means even if people abuse or mistreat them their country can't mount a counterattack. Which has led to a group people making them into slaves.
They have low combat stats, more like healer attributes. That's why the MC had to corrupt his people, hence, the black wings, so they could be stronger and eventually became the no.1 empire.
Can anyone tell me why people with wings are treated badly?
