Baator

This is it: the Big One, the Nine Hells, the Pit of Darkness, the Stinking Mire, whatever. It's got more names than there are prime-material worlds. It's the plane of the most dangerous evil there is: the baatezu -- or, more commonly, "devils" - fiends of unsurpassed power. These monstrous beings are absolute masters of their plane. Among their kind exists a rigid hierarchy of domination that defines all life on Baator.

The most vile petitioners consigned to this plane are transformed into larvae - grub-things found throughout the Lower Planes. All petitioners endlessly suffer the tortures of the baatezu, for the wretches can never truly die by torment. Their burnt, broken, and bleeding carcasses reform within a day and the entire process begins again. The petitioners endure this in the hope that someday they will advance and torture others.

Along the Great Road, Baator is between Acheron and Gehenna.

Note: Baator originally appeared in the Planescape AD&D campaign setting from TSR. Its use here is for the purposes of providing context for the campaign only.
