Mistress Mayven, also known as the Mistress of The Mire, is a malevolent Sea Hag and a vital member of the Coven of the Pearl. Once a prominent figure within the Eldar Court and deeply infatuated with Avatar Typhon, her story took a dark turn when she became consumed by her desire for power and the arcane might of the Penitent Pearl.

Driven to madness by her insatiable lust for power, Mistress Mayven's transformation was as physical as it was mental. Her once-beautiful Unknown visage was twisted into a grotesque form resembling an electric eel. But it was her mind that truly became corrupted, as she developed a dominatrix complex and a thirst for absolute control over the inhabitants of The Sea Realm.

In her quest for dominance, Mistress Mayven betrayed her former lover, Avatar Typhon, and sought to subjugate all who resided within The Sea Realm to bend to her will. Her actions, along with those of her fellow Coven members, set into motion a dark and sinister plot that threatened the very fabric of Atla and its surrounding waters.

Mistress Mayven's legacy is one of treachery, madness, and an insatiable hunger for power that ultimately led to her downfall and her transformation into a malevolent sea hag. Her story serves as a cautionary tale of the corrupting influence of unchecked ambition and the dire consequences it can bring.
