Gnoll Fang of Yeenoghu
Source: Monster Manual (2024) p. 141

Gnolls possessed by demonic vestiges of the demon lord Yeenoghu, fangs of Yeenoghu direct the chaos of gnoll packs. Along the way, these fanatics seek grisly omens from Yeenoghu and strive to interpret the demon lord’s vicious goals.
Gnolls
Fiends in Feral Flesh
- Habitat. Desert, Forest, Grassland, Hill
- Treasure. Armaments, Individual
The first gnolls arose from hyenas that fed on flesh tainted by the Abyss. Their corruption and violence delighted the demon lord Yeenoghu, who encouraged their numbers and spread them across the multiverse. Ever since, gnolls have been the cackling servants of Yeenoghu, existing to cause ruin and to feast on what remains.
A quote from Iggwilv
Yeenoghu claims gnolls not as his brood but as maggots purposefully released to infest a despised carcass. They are a pernicious rot the Beast of Butchery spreads across mortal worlds. Whatever they once were, they were remade and are now his.
