Baator

The Nine Hells of Baator inflame the imaginations of travelers, the greed of treasure seekers, and the battle fury of all moral creatures. It is the ultimate plane of law and evil and the epitome of premeditated cruelty. The baatezu, or devils, of the Nine Hells are bound to obey the laws of their superiors, but they rebel within their individual castes. Most undertake any plot, no matter how foul, to advance themselves. The Dark Eight are the generals of the baatezu armies in the Blood War. Ruling over each layer are the Lords of the Nine. At the very top of the hierarchy is Asmodeus, who has yet to be bested. If he were to be vanquished, the victor would rule the plane in turn. Such is the law of the Nine Hells.
