Beneath the black waters of the Western Sea lies the forgotten temple of Neryth — the Drowned God. Once worshipped as the master of tides and storms, he was betrayed by mortals and cast into the abyss, his voice silenced for centuries. Yet the ocean remembers… and it waits. When a violent storm batters the remote fishing village of Rynmar, an obsidian conch washes ashore — an artifact whispered of only in old sailors' tales. Young historian Lian feels an inexplicable pull toward it. The moment his hands close around the relic, he hears the first echo of a voice that should not exist: the Drowned God's testament. Joined by Seran, an exiled sea captain seeking redemption, and Maris, a mysterious mute girl who can breathe beneath the waves, Lian sets sail into uncharted waters. Their journey leads them through cursed shipwrecks, sunken kingdoms, and ancient sea rituals older than human memory. Each step draws them closer to a revelation that will shatter their understanding of faith, loyalty, and fate itself. The testament promises salvation — but at a cost none of them are prepared to pay. In the depths, truth is never what it seems, and some bargains cannot be undone. The Drowned God's Testament is a sweeping mythic fantasy of ocean-born legends, haunting prophecy, and the terrible price of destiny — culminating in a final choice that will decide the fate of both sea and shore.
