The Beast of Butchery appears as a great scarred gnoll, towering 14 feet tall. Yeenoghu is the Gnoll Lord, and his creations are made in his twisted image.
When the demon lord hunted across the Material Plane, packs of hyenas followed in his wake, and those that at of great Yeenoghu’s kills became gnolls.
Few others worship the Beast of Butchery, but those who do tend to take on a gnoll-like aspect, hunching over and filing their teeth down to points.

Yeenoghu’s lair in the Abyss is called the Death Dells. Its barren hills and ravines serve as a hunting ground, where he pursues captured mortals in a cruel game.
Yeenoghu’s lair is a place of blood and death, populated by gnolls, hyenas, and ghouls, and there are few structures or signs of civilization on his layer of the Abyss.
The challenge rating of Yeenoghu is 25 (75,000 XP) when he’s encountered in his lair.

Any creature in the space where the spike emerges must make a DC 24 Dexterity saving throw.
On a failed save, the creature takes 27 (6d8) piercing damage and is restrained by being impaled on the spike.
A creature can use an action to remove itself (or a creature it can reach) from the spike, ending the restrained condition.
Pack Rush: Each gnoll or hyena that Yeenoghu can see can use its reaction to move up to its speed.

Carcasses of prey are left to rot in an unnatural display of wasteful slaughter.
Spiky Terrain. Within 1 mile of the lair, large iron spikes grow out of the ground and stone surfaces.
Yeenoghu impales the bodies of the slain on these spikes.
If Yeenoghu dies, these effects fade over the course of 1d10 days.
