Based on Aqua Rose’s knowledge about the authority of Barons, aside from being able to purchase private territory within White River City, they could also hire their own guards. A Baron could hire a total of 10 NPCs to serve as guards for his own territory.
However, a Baron was the lowest rank of nobility.
Only when one was promoted to Viscount would one be counted as one of the true nobles of the city.
A Viscount could not only purchase private territory, one could recruit up to 40 NPCs as guards, as well as have two personal guards.
Having personal guards was a special privilege available only to true nobles.
