There are all kinds of adventures in the realm of nature
Each race that belonged to the Realm of Nature had its own style of governance. The elves, for example, had two kingdoms with two kings, but shared a common law. Druids used to have a kingdom that governed over their nomadic tribes, but now, it was just the Council of Chiefs and Elders who held the law and authority.
The drows, meanwhile, had their city-state.
Each underground city was ruled by a mayor, who was elected by the citizens. Each city had its own laws and rules, although there was a general list of commandments that should be abided by while they made the rule.
I was honestly surprised to find an election system in this world.
Consequently, the visitors had to search in advance what rules applied in what city, because it might differ, and with that, the vibe of the cities was also different. There were cities with a very strict law, and there were cities with a loose one--just as long as they abide by the commandments.
