This place once used to be property of the Orcs, and it used to be called the Bloody Marsh, thick with plantlife, but once the Trolls came and blasted the entire continent, the marsh became but a Savannah, but it is still the most notable one in the entire desert. The Gnolls had later on settled here, and started forming permanent villages, unlike most others, who live nomadic lives, nesting from oasis to oasis. The Gnolls have a tribal culture, and are highly dependent on the blessings from their Gods, which mostly revolve about hunting and battle.
The Gnolls possess extremely low technology, for they still rely on wood and stone, as well as making leather clothes, and shields made from cow skin, but they are not to be underestimated in battle. Their senses are extremely keen, and they are lightning fast. They ride on top of giant canine beasts, as well as an occasional war elephant. Also, before each battle, their Shaman preform some weird rituals, making potions from crushed animal bones and herbs, which are believed to grant them special abilities. It is true that Gnolls have no wish of conquest or control, and are usually targeted by Reptillions, to be brought in as slaves, but if they must, they will fight with fang and claw. And if they are the ones doing the hunting, then you may as well pray that they ignore you, for that is the only way to escape.
