The third chapter of Call of the Sea, titled The Vanishing of the Lady Shannon, introduces players to complex environmental mechanics and intricate multi-step puzzles. Exploring the shipwreck site requires careful observation, as clues are scattered throughout the abandoned camp and nearby caves. Understanding how these mechanics interlock is essential for uncovering the fate of the expedition and progressing deeper into the island's mysteries.
Powering Up the Ship Generator
Restoring power to the stranded vessel is your primary objective upon arriving at the crash site. Inside the hull of the ship, players will encounter a power generator mechanism that requires activating levers in a specific sequence. Pulling lever 3 first, followed by 2, 4, and finally 1 will successfully jumpstart the electrical circuit.
Once power is restored, the surrounding camp area and nearby cave structures become fully operational. This allows you to interact with key equipment, including projectors and field tools, which provide critical clues for subsequent puzzles.
Solving the Floating Stones and Resonance Puzzle
Inside the shipwreck, players encounter a unique mechanism involving three suspended floating stones. The goal is to adjust the frequency so that all three green symbols illuminate simultaneously. Completing this resonance challenge prompts Norah to record crucial numerical coordinates in her journal.
These numbers directly correlate with symbols found later in the chapter. Carefully reviewing your journal entries ensures that you retain the precise alignment necessary for future decryption steps.
Decoding the Tide Chart and Projector Clues
Further exploration reveals a small cave housing a projector setup and a piano contraption. By comparing the water-level mark located near the main pit with the slides in the projector, you can identify the exact sea level measurement. Matching this level with the calendar found behind the ship clarifies the correct date setting.
Using the piano keyboard helps map the symbols to corresponding numerical values recorded earlier. This step acts as a Rosetta stone for the remaining mechanical barriers in the area.
Opening the Water Valves and Bridge Path
With all necessary information translated, proceed to the valve controls around the central pit area. You must open the three valves that correspond directly to your translated symbols while leaving all other valves firmly closed. Next, set the main pit valve to the solid black circle to align with the new moon phase.
Activating the central pedestal mechanism triggers the stone pillars to shift, forming a permanent pathway across the chasm. Crossing this newly opened bridge allows Norah to access the inner stone gate and conclude the third chapter.
