Devil
Each type of devil plays a particular role in Hell’s bureaucracies and hierarchies, though some have far more specialized functions than others.
The Hierarchy of Hell
Hell is a harsh plane of law with little use for compassion or empathy. As such, it exists entirely within a strict hierarchy, and this order extends to its denizens. While different types of demons correspond to various sins and daemons are associated with modes of mortal death, the different types of devils exist solely to fulfill particular roles in the infernal machine. On occasion, a particular devil can transcend the role for which they were literally shaped, but this often transforms the devil physically into the type suitable for their new role.
Hellfire
Stinking, sulfurous hellfire is infused with evil. Hellfire always deals a combination of fire damage and evil damage, though the specific ratio depends on the hellfire’s origin. Certain types of hellfire can impose other effects on creatures as well, such as sapping their strength or memories.
Hellmouths
While travel to and from Hell is possible with plane shift, another way to reach and traverse the infernal realms is via hellmouths, strange living portals connecting different layers or even different planes. A hellmouth takes the form of a grimacing face, distended maw, or other distressingly organic aperture, and no two share the same appearance. Most are carefully guarded, but some new or well-hidden hellmouths have yet to be discovered.
Queens of the Night
The four queens of the night wield great power in the Pit. Ardad Lili is a plotter and manipulator with ambitions of ruling the heavens, while Doloras revels in suffering. Most distant is Mahathallah, watching over fate and death. Mightiest among them is Eiseth, who is assembling an army in Dis in the hopes of claiming the iron throne of Malebolge
.Hamatula (Barbed Devil)
Hamatulas are forged in Erebus to protect infernal vaults from those foolish enough to try to rob the archdevil Mammon. In case the vicious spines protruding from their bodies and ability to teleport weren’t deadly enough, they are also clever wielders of warding glyphs. They are effective conjured guardians, though they resent being pulled away from their duties in Hell. Unlike most fiends, hamatulas are formed from several souls that lack any features distinctive enough to merit another role.
Hamatula Treasures
Perhaps because hamatulas exist to guard the riches of archdevils, infernal dukes, and queens of the night, they find themselves drawn to wealth. Though they despise summoners who pull them away from their assigned duties, hamatulas use their servitude as an opportunity to collect treasures and wealth that they can offer to their lords upon their return. Treasures that are painful or dangerous to handle are among their favorite prizes.
