Gnolls are a tribal race who hunts in packs, half man and half hyena. Many packs of Gnolls roam into human lands to escape Orchish persecution in the Weald, but are met with an even harder time within The Broken Kingdom.
It is within Gnoll nature to hunt, and so they often raid human settlements and farms, killing any in their way and taking women back to their camps. They, like Orcs, worship Gruumsh, and are known to leave their dead enemies butchered and nailed to walls in offering to him.
Gnolls are not a threat to the sovereignty of the land, but are a menace in rural areas away from large cities and garrisons, where local militias are the only forces around to deal with their packs.
