Gnoll

A gnoll is a humanoid creature stretching up to about seven feet tall. They are carnivorous humanoids, known for their savage culture and warlike ways.

Gnoll Pack Lord
The alpha of a gnoll pack is the pack lord, ruling by might and cunning. A pack lord earns the best of a gnoll pack's spoils, food, valuable trinkets, and magic items. It ornaments its body with brutal piercings and grotesque trophies, dyeing its fur with demonic sigils, hoping Yeenoghu will make it invulnerable.

Gnoll Witherling
Sometimes gnolls turn against each other, perhaps to determine who rules a war band or because of extreme starvation. Even under ordinary circumstances, gnolls that are deprived of victims for too long can't control their hunger and violent urges. Eventually, they fight among themselves.

Society
Traveling in small, roving hunting packs of half a dozen at a time, these humanoids are generally seen on the outskirts of civilization.

Although they are easily provoked into violence, large-scale raids against points of civilization, are generally too dangerous for their small packs, and they would only dare to do so out of desperation.

Aggressively hungry creatures, gnolls would eat what flesh they could get a hold of, though they are known to be opportunistic hunters, keeping to small game and the occasional person who wandered too far from their fields. On occasion when food is scarce, it is not uncommon for gnolls to turn to cannibalism in their obsessive hunger. Feeding on each other, gnolls would pile up the bones of the dead whose flesh they had devoured.

Worship
Worshiping dark powers, the gnolls were seen to have banners made of flesh with the mark of a demon lord of the Abyss called Yeenoghu. Through rituals performed in the name of this patron, the gnolls were able to take the corpses of the fellow gnolls they had consumed and raise them up as undead warriors in their service.

Yeenoghu
A demonic lord of the Abyss, Yeenoghu was a large, feral, bestial demon that had once roamed the Prime Material Plane. He was ever hungering, and ever wandering to conquer and devour all in its wake, leaving destruction, fetid meat, and wave and waves of yipping, angry hyenas that would devour what was left behind.

Known Gnolls
When the Mighty Nein adventuring party encountered gnolls in Alfield, they had muscular torsos, thin dog-like legs, extended necks with spots of fur, ears curled upward, and dog-like snouts. They were strong and able to rapidly dart and leap across areas. They communicated in yips and growls and had a hyena-like laugh. As well as their bite, they used spears and longbows. They wore patchwork hide and leather armor over mangy fur that was coated in thick, oily liquid smelling of acrid, rotting flesh. After this encounter the Mighty Nein tracked the gnolls to their Lair in Rill's Mouth Mines.
