Archomentals are powerful exemplary beings of the Elemental Planes and rulers over the elementals. Although they are not truly rulers of their planes, archomentals like to consider themselves as much and often grant themselves regal titles like Prince or Princess. They are compared in the source material to the archfiends or celestial paragons, and are considered to be the elemental equivalent of such beings.
The evil archomentals are collectively known as the Princes of Elemental Evil. The five most famous include:
- Cryonax: Prince of Evil Cold Creatures
- Imix: Prince of Evil Fire Creatures
- Ogrémoch: Prince of Evil Earth Creatures
- Olhydra: Princess of Evil Water Creatures
- Yan-C-Bin: Prince of Evil Air Creatures
Two further archomentals, Uzrith of Earth and Alyolvoy of Water, are mentioned in "The Mud Sorcerer's Tomb" in Dungeon #37. They are powerful and possessive evil elemental beings who created at least one of seven magical vessels called the Ships of Earth and Sea, which have the ability to move on the earth and underwater as well as on the surface of the sea. The two are fierce rivals of one another.
The good archomentals are collectively known as the Elemental Princes of Good. The four most famous include:
- Ben-Hadar: Prince of Good Water Creatures
- Chan: Princess of Good Air Creatures
- Sunnis: Princess of Good Earth Creatures
- Zaaman Rul: Prince of Good Fire Creatures
Three other archomentals are first mentioned in Manual of the Planes (1987).
- Bwimb: Prince of Ooze Creatures
- Chlimbia: Prince of Magma Creatures
- Ehkahk: Prince of Smoke Creatures
Similar beings ruling the quasielementals include:
- Gazra, "the Shifting Emperor," a lord of the quasielemental plane of Ash.
- Crystalle, Lord of Minerals, the most powerful of the mineral quasielementals.
- Alu Kahn Sang, a chaotic evil dust quasielemental. This High General or the Wind of Destruction leads a legion of other dust quasielementals on a campaign of destruction and violence.
- Ty-h'kadi, Prince of Thunder and Lightning, Lord of Storm Elementals.
- Sun Sing, Viceroy of the Vacuum.
