Tyranny of Dragons
The Nine Hells, sometimes Hell or Hells, also known as Baator in Infernal, is the home of the devils. It is a plane of sinister evil and institutional cruelty organized in a strict caste system with a very rigid chain of command. Unlike the demons of the Abyss, the devils are highly organized in their quest for power and status: scheming and plotting power plays, coups, and assassinations. Each of the nine Hells has its own physical laws or properties of matter but all are inhospitable or deadly to outsiders. This plane’s place in the cosmology of the Forgotten Realms has shifted over time but is always a bastion and incubator for those of the lawful evil persuasion.
