Leo carries the pure bloodline of an ancient Sea God, but crippled his own legs to save his fiancée's father. On the eve of their wedding, Sophia and Arthur, the Papacy's Saint, drag him to a cliffside altar and drain his divine blood so Arthur can be baptized a Saint. Left for dead, Leo instead awakens a sleeping god-relic beneath the sea, reclaiming the Golden Trident and a body reforged in scaled armor. He returns in disguise, crushes Arthur's forged relic in the arena, and reveals his true god-form, forcing the Church to its knees. Allied with Elena, Grand Duchess of Winter, he hunts down three Sea God Hearts, exposes the Church's dark sacrifices to the Lord of the Abyss, and ultimately unleashes the wrath of the ocean to seal the rift and save the continent.
