Haven City is basically a large hellhole for the vile and scum people alive. The kingdom will send most of the detained criminals to the city and let them have freedom and free reign over the place. One thing the city respects the most is the farmers who are assigned to cultivate small gardens and raise livestock.
These farmers are also criminals but everybody respects and treat them with the utmost care, for they are the only people that bring food to their table. But there is also another source of food, importing them from the
outside world.
"It is recorded that no Estarians had ever been successful in climbing
over that wall that is about fifty meters tall."
One can raise their head all the way up to the point that it would hurt but they will barely see what's at the top of the thick impenetrable wall.
