Baphomet

Baphomet is a demon lord who rules a layer of the Abyss called the Endless Maze. He is the Prince of Beasts and the Demon Lord of Minotaurs, an embodiment of savagery and an insidious force that worms its way into the heart of his followers to deceive them into embracing brutality.
Baphomet has the appearance of a 12 ft (3.7 m) tall humanoid with a bull's head, a bovine tail, and broad, stubby hands and feet. His body is covered with coarse black hair. His horns curve downward and outward.
Baphomet's realm is the Endless Maze, a layer of the Abyss, supposedly infinite in size. Here, Baphomet dwells in his palace, the Lyktion, and spends his time creating various new demonic breeds in his infamous Tower of Science. Some of his more successful creations sre the goristroi, the bulezaus, the ghours, and the feral ankashars.
Baphomet hates Yeenoghu, and the two are bitter enemies. They've warred against each other for as long as they can remember, and both have forgotten the origin of their feud.
Baphomet has a multitude of minotaur, ogre, and giant followers and minions. He is also served by ghour demons, a race of demons resembling burly, hairless minotaurs that commanded troops of these mortal minions. He seeks to use them to further his schemes, notably to gain the upper hand in his battles against Yeenoghu. A multitude of other twisted creatures revere Baphomet as well, some becoming his thralls, and if they pleased their bestial patron, they would be granted rulership of a portion of the Endless Maze. Those who displease Baphomet are eaten.
Like all demons Baphomet has only limited influence over the mortal realm of Andorra, notably through his cults and followers. No demon has ever escaped the Abyss and gotten any further than the devil hellscapes of Bataar without being defeated and sent back.
