The Gnolls and some small dwarven settlements are the primary makeup of the continent of Edhen. The Gnolls are the native race to the continent and have the dominant governing system.
The Gnolls control much of the land, nearly 80%, and the rest is split up among other racial and mixed race settlements, however, all are still quite often subject to the ruling of the Gnoll Captains.
The Gnolls rule themselves in tribal groups, called packs, each with a Captain who acts as a leader and decision maker, as well as a military strategist. While there are no overseeing powers, and all the packs work independently, in times of war, the packs all unite and are extremely efficient at working together in coordinating extremely well thought out military strategy.
