New Approach

The next day, Kahn and the group decided to depart in different directions and take a city tour around Alfheim. The main purpose was to learn everything useful that they needed to know to perfectly mix with the populace and understand how everyone behaved or conducted themselves in their day-to-day life. 

Kahn wasn't oblivious to the fact that what could seem outrageous or immoral to you, could just be a normal code of conduct in different cultures or civilizations. And being ignorant about such details would just leave a lot of plotholes in their storyline.

And while taking notes of locations of monasteries, historically important places, authorities and the overall layout of the city that spanned 150 kilometers in perimeter alone… Kahn came to know about one odd thing. 

Slavery. 

Yes, the Elven Empire legally allowed slavery. 

However, it was not like selling people and the owner gets to do whatever the hell they want with them.
