📖 Complete Storyline (Full Detail)
🔄 The Call from the Sea (Ch. 307–315)
Through the Tarot Club, Alger reveals troubling developments within his Church of the Lord of Storms. A mysterious cult has been gaining influence in the coastal territories, claiming to worship a Sea God believed to be an ancient, forbidden existence. Their activities include rituals at sea and the summoning of strange marine creatures.
Klein recognises the danger—ancient deities and their remnants often carry corruption capable of destroying entire communities. He encourages Alger to investigate but warns him to maintain his cover.
🔄 The Cult’s Rising Influence (Ch. 316–325)
Alger’s position as a sailor and low-ranking church official grants him access to sensitive information. He discovers that the Sea God Cult has infiltrated coastal trade routes, bribing ship captains and even some naval officers. The cult’s rituals grant supernatural blessings to ships loyal to them, making them difficult to challenge.
Meanwhile in Backlund, Klein continues building his network, using his connections to funnel resources and mystical knowledge to Alger through the Tarot Club.
🔄 Deep-Sea Mysteries (Ch. 326–335)
Reports begin surfacing of ghost ships—abandoned vessels adrift at sea, carrying signs of ritual sacrifice. Alger boards one such vessel and finds it littered with strange seaweed and covered in arcane symbols. The only clue: a ceremonial dagger inscribed with the Sea God’s name.
The investigation reveals that the cult seeks to awaken an ancient sea-bound power, possibly a fragment of a true deity. Alger relays these findings to Klein, who immediately begins researching ways to counter such beings.
🔄 The Betrayal at Sea (Ch. 336–345)
A sudden twist hits Alger when a supposed ally within the Church betrays him, revealing his interest in the Sea God Cult to cult sympathisers. Alger is ambushed during a voyage, forced into a desperate fight aboard a rocking ship during a storm.
Using a mix of cunning, combat skill, and sheer determination, Alger escapes, but at the cost of exposing himself as a dangerous player in the maritime power struggle.
🔄 Cult Confrontation (Ch. 346–355)
With guidance from Klein, Alger infiltrates a major Sea God Cult ritual disguised as a loyal follower. The ceremony takes place on a remote island shrouded in perpetual mist. The cult leaders attempt to call forth a massive oceanic apparition—half deity, half nightmare.
Alger sabotages the ritual at a critical moment, unleashing chaos among the cultists. Storms rage, the sea churns violently, and the apparition vanishes before fully manifesting. Alger barely escapes alive, carrying stolen artifacts and critical intelligence.
🔄 The Aftermath (Ch. 356–360)
The Sea God Cult suffers a heavy setback but is far from destroyed. Alger earns both allies and enemies from his actions, with whispers of his deeds circulating among sailors and pirates alike.
Klein, from his position as The Fool, consolidates the information Alger brings, piecing together the greater threat these sea cults pose—not just to maritime trade, but to the entire Loen Kingdom.
