Egeria

Gender: Female
Titles: Hydro Archon, Mistress of Many Waters, God of Justice
Region: Fontaine
Affiliations: Palais Mermonia, The Seven

Egeria, also known as the Mistress of Many Waters, was the original Hydro Archon of The Seven, who presided over Fontaine. She was the predecessor of the latest Hydro Archon, Focalors.

Egeria assumed control of Fontaine after the fall of Remuria and the death of its God King, Remus. She died in battle at Tunigi Hollow during the cataclysm 500 years ago and her body turned into the water of the Amrita. Greater Lord Rukkhadevata grew the Harvisptokhm from the Amrita to anchor Egeria's consciousness to the mortal realm, allowing Egeria to contain and cleanse the Abyssal defilement in the Girdle of the Sands.
