Olhyrda, the Princess of Evil Water Cretures, is an archoelemental from the Plane of Water. Arguably the most powerful of the archoelementals, she seeks divinity, attaining it through the worship of a multitude of wicked creatures that declare her as a goddess on many worlds.
Olhydra appears as a constantly crashing wave some twenty feet in diameter, forming a face and limbs out of the elemental stuff of her composition. She dissolves and reforms in a constant cycle.
Olhydra is served by an army of water elementals, and also by numerous wicked aquatic creatures, including sahagin, vodyanoi, seawolves, and eyes of the deep, among others. Her greatest allies are her massive forces of water wierds, which torment people throughout the plane.
