Legia hailed from the serene merfolk race, celebrated for their tranquility and harmony. Renowned for her unparalleled beauty and enchanting voice, she was expected to unite with the king of her people. However, beneath her graceful exterior, Legia harbored a clandestine obsession with magical power. While her fellow merfolk were content with their peaceful existence, she yearned for deeper knowledge and mastery of the arcane. Sequestered in her secret grotto, she immersed herself in the study of potions and spells, dismissing her kin as simpletons and seeking to uncover the mysteries beyond their tranquil domain.
During one of her clandestine expeditions, Legia discovered a mysterious rift in the ocean floor near a forbidden trench, a place her people avoided due to its rumored dangers. Her fascination with the rift led to frequent explorations, arousing suspicion among her kin. When the king's guards discovered her transgressions, Legia's defiance resulted in a desperate escape attempt. Injured and cornered, she used her blood to awaken the trench's lurking denizens, triggering a cataclysmic transformation into a monstrous being with tentacles. Enraged and empowered, she unleashed her fury upon her pursuers, only to be sealed within the trench by the king's ancient spell. Trapped for centuries, Legia's existence became a cycle of predation and boredom, her memories fading as she longed for freedom. Her chance for escape arrived with Cideous Kaliban, a tiefling sailor whose infernal blood made him an ideal vessel for her. Through him, Legia saw an opportunity to break free from her watery prison and explore the world anew, fulfilling her insatiable hunger for power and understanding.
