Archomentals are a storied race of beings from Dungeons & Dragons. They are essentially the "exemplars" (gods/leaders) of the Elementals.
Gary Gygax created the first archomentals - or, as he called them, "Princes of Elemental Evil" - in this edition. They basically served the same purpose as demon lords and arch devils, but for the elemental planes of Earth (Ogremoch), Fire (Imix), Air (Yan-C-Bin), Water (Olhydra) and Cold (Cryonax). These appeared in the Fiend Folio sourcebook.
Planescape brought the archomentals back and gave them counterparts (since this was the Grid-Filling Edition), the Princes of Elemental Good; Sunnis of Earth, Chan of Air, Ben-Hadar of Water and Zaaman Rul of Fire. None of them made an appearance until the 3rd of the Planescape Monstrous Compendium Appendixes, which focused on the denizens of the Elemental Planes. Why did they go out of their way to fill this grid without adding a Good-aligned Ice archomental or any Archomentals at all for any of the other three paraelemental planes? Good question!
The Archomentals were given their official name of "Archomental" in Dragon Magazine for this era, with the Archomentals of Evil appearing in Dragon #347 and their Good counterparts appearing in Dragon #353. This edition also introduced the concept of Archomentals of the Paraelemental Planes, though only five are mentioned (Bwimb of Ooze, Ehkahk of Smoke, Chilimba of Magma and Cryonax of Ice) and only Cryonax got stats.
In 4e, archomentals, renamed "Primordials", got a HUGE promotion. With Points of Light mythos styled after ancient Greco-Roman myths, the multiverse was now created originally by the Primordials/Archomentals, with the Gods coming along later and adding permanency and mortal life to everything. This ticked off the Primordials, and so they fought the Dawn War. The gods killed and imprisoned a huge bunch of Primordials, and others were corrupted into the first Demon Lords, and so the Dawn War came to an end.
Because 4e went for the Elemental Chaos rather than the rigid grid-system of Planescape and its Elemental, Quasimental and Paraelemental Planes, its Primordials were a very diverse bunch, with figures like Atropus (imagine a frigging planet made of undead flesh 'n' bone and you got the right idea), Iktha-Lau (embodiment of deep space and the empty void) and Mual-tar (a freaking huge-ass dragon-thing of stormclouds and lightning chained down by rune-etched chains with links the size of castles).

The original Archomentals are back in a huge way, serving as the final bosses of the Princes of the Apocalypse story book from Wizards itself. This being the Nostalgia Fueled Edition, they've reclaimed their titles of "Princes of Elemental Evil" and are once more the servants/partners/minions/spawn of Tharizdun in his guise as the Elder Elemental Eye. They have statblocks, and while they're nerfed a bit from their old forms, they can still murder whole parties thanks to their absurd AOE abilities. Cryonax isn't kicking around much, but the other four are still active and trying to vigorously expand their cults by preying on mentally unbalanced adventurers in the Forgotten Realms and Greyhawk. Cryonax does get a mention, though, as potentially being controlled by a powerful magic ring that Frost Giants spend all of Storm Kings' Thunder and Tomb of Annihilation trying to steal.
Pathfinder's equivalent is known as the evil aligned Elemental Lords and the good aligned Elemental Dukes. The Elemental Lords have imprisoned the Elemental Dukes in magic gems, but the Pathfinder Society freed Ranginori as part of 2017's organized play season.
- Ayrzul, the Fossilized King
- Hshurha, Duchess of All Winds
- Kelizandri, the Brackish Emperor
- Ymeri, Queen of the Inferno
- Atreia, The Lambent Prince
- Ranginori, Duke of Thunder
- Lysianassa, Empress of the Torrent
- Sairazul, the Crystalline Queen
These eight don't appear to be the only demigods of the elemental planes though. Feronia is described as a neutrally aligned demigod from the plane of fire. She was once briefly the wife of Archdevil Dispater, a union that is best known for producing Ragathiel, the
Archangel Empyreal Lord of vengeance and righteous RAGE.
