Design details

Olhydra is an archomental in the Dungeons & Dragons fantasy role-playing game. Her symbol is a blue-green square. It's possible that Alyolvoy, an evil archomental of water mentioned in Dungeon #37,^[1] is an alias of Olhydra.

Publication history

Olhydra first appeared with the elemental princes of evil in the original first edition Fiend Folio (1981), created by Lewis Pulsipher.^[2] Olhydra was one of the main antaognists in Frank Mentzer's 1982 RPGA module The Egg of the Phoenix,^[3] which was later included as part of the expanded 1987 adventure compilation, Egg of the Phoenix.^[4]

Olhydra appeared with the evil archomentals in the second edition book Planescape Monstrous Compendium Appendix III (1998).^[5]

Olhydra appeared with the evil archomentals in the third edition in Dragon #347 (September 2006).^[6]

Description

Olhydra appears as an endlessly breaking wave of water, an amorphous blob with almost-human features buried within its depths. She is about 20 feet wide and weighs 5,000 pounds. She may also appear as a feminine, half-human and half-pleiosaur creature with tentacles for hair and a semi-transparent liquid body.

Relationships

Olhydra harbors an intense hatred of Imix and schemes to destroy him. Along with Imix, Yan-C-Bin, and Ogrémoch, she once pursued the artifact known as the Egg of the Phoenix. One of her greatest allies is Dagon, and rumor has it that she and Dagon may have spawned twin daughters. She occasionally comes into conflict with Blibdoolpoolp, Eadro, and Persana, but gives little thought to Ben-hadar.

Olhydra is served by undead dinosaurs, kapoacinths (aquatic gargoyles), evil water elementals, water grues, water mephits, orlythys, renegade hezrou that she's lured away from Demogorgon, tojanidas, callers from the deep, and lesser water weirds. A triad of sea hags known as the Blue Coven also serves her; the three have merged into an entity with three bodies and a single mind.

Realm

Olhydra lives in the ruins of a castle made of living black coral, submerged in a great indigo lake, on the Elemental Plane of Water.

Worshipers

Olhydra's faithful include aboleths, sahuagin, scrags, anguillians, sea hags, krakens, seawolves, eyes of the deep, and many more. Pirates, wicked sea druids, and mariners flock to her cause, and she has one of the biggest followings among the evil elemental cults.

Clerics

Olhydra's clerics, those who wear clothes, wear robes with blue trim. Many carry around small jugs of sea water for the purpose of special ceremonies and blessings.
