Gnoll Demoniac
Source: Monster Manual (2024) p. 141

Gnoll demoniacs are berserkers that arise from gnolls who’ve ritualistically fed on flesh corrupted by the Abyss. Now embodying the ruinous hunger of Yeenoghu, these gnolls throw themselves into battle, heedless of odds or their own survival. Rampaging demoniacs even devour other gnolls in their wild frenzies.
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.
