A kingdom where, if there are multiple princes (princesses can't rule unless they have no siblings), the princes fight to the death in the arena to decide who gets to rule. A simple way to make sure your brother cannot make a bid for the thrown, and keeps the royal blood in one line.
In the inaccessible plateau of Hor-Nushan, there was always little crime. But in late autumn comes a maddening wind, that can drive the best man crazy, if only for a short time, make him turn on himself or others. For murder, the locals have devised a special punishment: the murderer has to dig a well for the family of his victim. The area is very dry, and having a good well is a source of wealth and prestige. In this way, the murderer atones for his deed and repays the family; perhaps they even find peace.
