In the wake of the mystery surrounding the dismantled warforged sentinel, the atmosphere aboard the ESS Albacore turned from professional isolation to active paranoia. During a lunch following the initial interrogation, the sailor Nicola Cornelius began openly sowing seeds of distrust among the party members. He revealed that Captain Carver possessed a notorious reputation in Europan naval circles for being a man who frequently returned from high-risk expeditions without his original crew or his vessel, suggesting that the current voyage might be following a similarly tragic pattern.

Further unsettling information was provided by Miyake Harrier, the Captain’s aloof twenty-year-old daughter. Despite her visible disdain for the passengers, she hinted that the ship's internal stability had been fractured long before the current mission began. She revealed that the vessel had experienced a moment of “near revolt” among its previous security detail, indicating that the simmering dissatisfaction among the crew was a chronic condition rather than a sudden development.

Seeking to maintain a veneer of normalcy, Captain Carver invited the traveling party to a formal officer’s dinner. The meal was attended by Carver, First Officer Drax Trulia, the Cascadian helmsman Warrick Drutha, and Officer Arthur Langdon. While the scene was punctuated by forced humor and professional courtesy, the party quickly realized the event was a thinly veiled informal interrogation intended to suss out if any of the passengers were involved in the sabotage of the warforged guard. The tension in the room was palpable as the party attempted to flip the questioning, seeking more information about Carver’s previous failed voyages, though their inquiries were largely deflected by the senior staff.

The dinner was violently interrupted by the screeching of metal and the frantic tolling of alarm bells echoing through the hull. The party rushed toward the source of the chaos in the engine room, discovering that the vessel’s complex boiler system—powered by bound water and fire elementals—had been compromised. One of the massive water elementals had been intentionally released from its containment housing, threatening to flood the engineering deck and kill the ship’s propulsion.

In a harrowing and deadly battle, the party engaged the primordial entity amid high-pressure steam and shifting machinery. While they were ultimately successful in re-containing the elemental and restoring the ship's systems, the incident provided undeniable proof that the Albacore was being targeted by a saboteur within its own ranks.

Following the battle in the engine room, the lines of loyalty aboard the submersible became sharply defined. Suspicion fell heavily upon Officer Trulia, who was observed in a series of shady, whispered exchanges with the engineer Sampson Hornblower. The party identified a clear schism in the crew: Drax Trulia, Hornblower, the dwarf Hothud Copperhood, and Nicola Cornelius appeared increasingly aligned toward mutiny, while Warwick Drutha, Drigg Bronzefinger, and Arthur Langdon remained abjectly loyal to the Captain.

The researcher Zachary Harrow and Miyake Harrier remained wildcards, their true allegiances obscured by eccentricity and silence. Furthermore, the party discovered a unsettling detail regarding the security force: the six warforged sentinels were each fitted with an arcane control bolt. These devices allowed Officer Langdon to override their free will via a master switch, effectively turning the stoic mechanical soldiers into an absolute extension of his command—a tool that would become a focal point for the coming struggle for control over the vessel.
