Savage and ruthless, Yeenoghu is the patron of all gnolls, He appears as a gaunt, 12-foot-tafl humanoid demon is covered with mangy patches of yellow fur and has pale gray flesh showing where the fur is absent. His face is thai of a leering, amber-eyed hyena, and he wields a massive flail with three spiked heads.
Yeenoghu is one of the lesser demon lords, yet he still commands a large empire on the 422nd layer of the Abyss, a region known simply as "Yeenoghu's Realm." He spends much of his time hunting lesser creatures or captured mortals and idly plotting assaults on the holdings of powerful demonic entities who are not themselves demon lords quite yet.
One of Yeenoghu's greatest and earliest triumphs was the subjugation of Doresain, the King of the Ghouls. Once a vassal of Orcus, the King of the Ghouls controlled his own layer of the Abyss until Yeenoghu's army invaded and conquered the layer and its undead ruler. The King swore fealty to Yeenoghu and continues to pay him homage to this day. Doresain still rules the White Kingdom today, but as a sworn ally of the more powerful Prince of Gnolls. Orcus's attention has been elsewhere, and so far, he has nor acted against the Prince of Gnolls for the theft of one of his subjects.
One of Yeenoghu's great desires is ro see to the prosperity of his people, the gnolls. He envisions a Material Plane dominared by his children, where elves and humans and dwarves and halflings are slaves at besr and food at worst. Yet he realizes that all the gnolls in the Material Plane could not achieve such a goal - as a result, he actively supports cultists oi other races who turn to him for support. The enigmatic leader of the Maure family once represented his most powerful cult among humanity at the time, yet internal strife caused by rival demon lord Malcanthet saw to the ruin of this resource. Today, Yeenoghu counts the Queen ot Succubi as one of his greatest enemies and periodically raids her realm. He is always turned back by her defenses, bur one day he hopes to gain enough allies to see to her ruin.
Only Yeenoghu's eternal war with Baphomet nears rhe level of his harred for Malcanthet. The source of the con flier between rhe Prince of Gnolls and the Prince oi Beasts Is unclear, likely forgotten even by the two demon lords rhemselves, yet they show no signs of ceasing their eternal hostilities.
Yeenoghu demands living sacrifices in remote wilderness regions on altars of crude stone. His faithful wear dark brown robes accented by mangy yellow furs. They are not allowed ro clean these robes, and in time they grow horrific with clorted blood and foul odors.
