Elves, the ones with the highest number and the highest potential (except a few rare races, of course) when it came to magic, were the ones who technically ruled the black tortoise empire.
They were fair and just, and they never showed any partiality toward anyone and treated everyone, at least in their empire, with respect. Or so was what people who were not from this empire thought.
It was true that elves were a race with virtuous hearts, and they couldn't stand injustice, but that was before they met humans. Once the black tortoise empire took in the humans, letting them all live with them, the peaceful races of the empire started to change.
They started awakening the traits of humans. They awakened arrogance, greed, lust, and many other things, changing their own nature, and that was something that remained within them now, years after the humans were kicked out of the empire.
