Many people think of Arab tycoons when chiefs or kings are mentioned, and thus subconsciously associate them with wealth, but this is not always the case.
Take the simplest example, the chieftains or landlords of Angola in the north are very rich because their land sits atop oil, but it can't be said the same for those in the south.
For instance, the kingdom Leonard Ethan is now presiding over as chieftain is just like that; apart from some land and granite suitable for building construction, there are no valuable minerals hidden beneath this land.
On the other hand, the location of this vast territory is somewhat remote, and there is not much woodland, so neither business nor selling wood is viable. The entire territory depends almost entirely on farming and animal husbandry and very little processing industry, which is to say it is extremely impoverished.
