Gnolls

Gnolls are infamous among races such as humans and elves for their brutality and demonic heritage. For the most part, they aren't wrong. Many gnoll packs are indeed aggressive and have a demonic side to their affairs. Typically they worship the demon lord Yeenoghu. They also tend to be rather aggressive and are still mistrusted and avoided. To them, the pack is more important than anything else.
Physical Description Demon-worshiping is not the only reason many races are wary of gnolls. A lean, muscular 7-foot tall gnoll can be an imposing sight. Despite their musculature, they move rather quickly, easily outpacing most other races. Gnolls also outpace most other races in how quickly they mature. A gnoll matures by the age of 5 and lives to be about 30. Oddly a gnoll's vitality will remain with them until very soon before their natural death.
Gnolls have reflective eyes that are typically bright green or yellow. They also have a thick coat of fur, which is generally light brown or dark brown. Certain clans may possess a single-colored coat or a spotted or striped coat. Some gnolls possess crest like manes of hair going from their head down their spine which rise up when they become frightened or angry.
Adding to other races distrust about gnolls, occasionally a gnoll's demonic ancestry will result in peculiar physical traits. This might be manifested in the claws of gnoll claw fighters or an abnormal eye or coat colors.
Gnolls are widely known as raiders and slavers. In the middle of the night, they attack a village or town, killing and eating guards and taking slaves. These slaves are then brutalized physically and mentally. This has become an art among many gnoll tribes. In fact, many gnoll tribes have “tantekurash” or “spirit breakers” who are experts at breaking the wills of slaves. If the slave resists, it is eaten. Occasionally a slave’s mind becomes so broken they revere the brutality of their gnoll captors. They then become “kryshantel” or “savage souls” who follow their gnoll masters into battle as thralls.
However, not all gnoll tribes are evil. There are a scattered few nomadic tribes who specialize as hunters and trappers. They may even come to peacefully interact with other races and often offer their service as hunters or trappers. Even so, they remain fairly aggressive and quick to anger, so other races have to be careful not to offend them.
Flind Gnolls In addition to the typical variety of gnoll, there is a sub-race known as flind gnolls. They tend to be shorter and stouter than other gnolls, use flindbars more commonly, and live in more hilly areas than other gnolls who live in plains. Flind gnolls can be either raiders or hunters as described above.
Society While there may be struggles within packs to determine who the alpha is, throughout these conflicts, both sides remain allies. To gnolls, the good of the pack is far more important than any personal glory. As a result, gnolls can be loyal to a fault to their chosen pack. In battle gnolls strive endlessly to prevent their packmates from being harmed, even taking an injury themselves.
Furthermore, a gnoll's mind is undeniably primal. They are natural predators and love the thrill and challenge of the hunt. This has resulted in a few traits in most gnolls. For the most part, gnolls prefer the wilds to any sort of urban area, though there are exceptions who see a city as a unique form of wilderness. Moreover, gnolls typically avoid diplomacy in favor of intimidating an answer out of others. It is simpler that way.
