In the Acadian Empire, slavery and human trafficking had long since been banned.
This was due to the Empire's foundational principles of freedom and equality for all the major races, whether mortals or Magi.
These principles have been upheld ever since the establishment of the Empire hundreds of years ago.
The founding Emperor wanted to promote a society where every individual, whether they were born with the blessing of mana or without, could thrive and contribute to the Empire.
However, despite the official ban, slavery still persisted in the shadows.
The slave trade remained highly profitable, especially for the Magi. After all, what better way to experiment with their magic spells than on a live conscious being? Dark Magi partook in such experiments the most.
Magi in positions of power exploited their influence to protect and profit from the slave trade. They ensured that it remained undetected and unpunished.
