Navigating the cosmic horrors of this Lovecraftian adventure requires a sharp mind and a steady hand. In this call of the elder gods walkthrough, we provide a detailed roadmap to help you guide Eevee Drayton and Professor Harry Everheart through a web of amnesia, ancient civilizations, and temporal displacement. Whether you are stuck on the intricate padlock of Eevee's journal or struggling to activate the Yithian vessel in the frozen wastes of Norway, this 2026 guide offers the exact solutions needed. By understanding the connection between the Great Race of Yith and the mysterious Dr. West, you can successfully close the loop and determine the fate of humanity.
Act 1: Everheart Manor and the Nightmare Journal
The journey begins with Eevee Drayton's search for answers regarding her recurrent dreams and a period of lost consciousness in 1956. Your first objective is to gather information in her room before traveling to Boston to meet the Dean of Archaeology at Mscatonic University, Professor Harry Everheart.
Video Highlights:
- Journal Unlock: How to solve the initial padlock puzzle.
- Manor Exploration: Finding the secret compartment in the Everheart library.
- Broken Statue: The first encounter with the Black Ooze.
Upon arriving at 5 Prospect Road, players will find the manor in disarray. To progress, you must navigate the library and the Professor's office.
| Location | Key Action | Reward/Outcome |
|---|---|---|
| Eevee's Room | Solve Padlock Puzzle | Access to Nightmare Journal |
| Library | Locate Ripped Canvas | Clue: "Sed Futura" |
| Office | Use Flashlight on Desk | Discovery of J. Xanic's Switchblade |
| Graveyard | Rotate Vase Face | Opens the way to Nora Everheart's Grave |
| Secret Room | Translate Latin Phrase | Clue: "Anticipate the Future" |
In the library, the frame reading "Sed Futura" is a critical hint. Rich families in the game often hide secrets behind their history—interact with the Everheart family portraits to reveal hidden mechanisms.
Act 2: The Rapahhanic River Caves Walkthrough
The search for the statues leads Eevee and the Professor to the Rapahhanic River Caves in Virginia. This section introduces the core puzzle mechanics involving ancient technology and the dangerous Black Ooze.
The Diving Suit
Locate the diving equipment near the underground lake. You must repair the wiring to get the air compressor running. Once active, Eevee can descend into the refinery.
The Refinery Murals
Examine the massive murals underwater. They act as blueprints for the towers. You will learn that the towers are not ruins but energy collectors powered by Black Ooze.
Tower Rotation
Use the collector system to channel the ooze upward. You must rotate the stone towers to align with the refinery's output.
The Piano Sequence
On the surface, the Professor finds piano-style keys. Playing the notes in the correct order triggers the tower's ascent. Playing them in reverse order triggers the opposite effect, which is necessary to fill the statues with orbs.
Do not let Eevee touch the liquid Black Ooze directly during the refinery segment. It causes immediate sanity loss and can lead to a Game Over if the exposure is prolonged.
Act 3: Escaping the Starry Wisdom Cult
After being kidnapped by Caleb Bowen, Eevee is held captive in the Starry Wisdom building. This section switches perspective between Harry's rescue mission and Eevee's forced psychic visions.
Harry's Rescue Route
- Pyramid Puzzle: Solve the Egyptian hieroglyph sequence to open the upper chambers.
- Lab Investigation: Develop the film in the biologist's office to find Bowen's location.
- Elevator Access: Use the developed photo to bypass security.
Eevee's Vision World
- Memory Retrieval: Navigate the Drayton Motors workshop in Benoa.
- Temporal Clue: Witness the meeting between Franklin Drayton and Harry in 1934.
- Coordinate Reveal: Identify the Yithian coordinates: 8-93-4-5.
| Puzzle Element | Solution/Clue |
|---|---|
| Starry Wisdom Pyramid | Align the sections to match Orion's constellation. |
| Nikotic Manuscript | Translates to "Nonlinear displacements toward the great library." |
| Trapezahedron | Do not touch the glowing crystal; it is a trap for the unwary. |
During this act, the name Dr. West is frequently mentioned. Pay attention to the cognitive patterns discussed by Caleb Bowen; they hint at the mind-swapping mechanics used later in the game.
Act 4: The Arctic Base and the Yithian Vessel
Traveling to Spitsbergen, Norway, Eevee and Harry must infiltrate a derelict Nazi research base to find the "Great Engineer." This area is a test of your ability to manage power grids and decryption.
Power Restoration Checklist:
Radio Station Objectives:
- Locate the generator key in the main hall
- Fix the sealed fuse box using the switchblade
- Activate the garage power switch
- Sync the antenna with the main control room
- Unlock the reinforced bunker door
| Device | Purpose | Solution |
|---|---|---|
| Enigma Machine | Decrypting Nazi orders | Use the code found in the worker's registry. |
| Fuse Box | Restoring local power | Connect the circuits to bypass the surge. |
| Control Panel | Moving the trap chamber | Align the trap to capture the Black Polyp creature. |
When Eevee connects to the machine in the bunker, her mind synchronizes with the Yithian Great Engineer. This confirms that her "dreams" were actually memories of her mind being swapped with an alien entity millions of years ago.
Act 5: Nakotus and the Final Sacrifice
The final act takes place in the ruins of Nakotus, located in the Great Sandy Desert of Australia. Here, the call of the elder gods walkthrough reaches its climax as you confront Caleb Bowen at the Basalt Tower.
The Tower Ascent Steps:
- Mirror Alignment: Use the polished Yithian lenses to reflect light onto the door sensors.
- Ooze Platforms: Step onto the stone slabs lifted by the Black Icor. Avoid the Polyps patrolling the lower levels.
- The Great Library: Navigate the ruins to reach the top of the Basalt Tower.
- The Choice: Interact with the Mind Swapping Device to trigger the ending sequence.
Ending Comparison Table
| Ending | The Sacrifice | The Result |
|---|---|---|
| Ending A: The Professor's Debt | Harry sacrifices himself | Harry reunites with Nora in the Icore/Englewood. Eevee lives. |
| Ending B: The Daughter's Legacy | Eevee sacrifices herself | Eevee reunites with Franklin Drayton in the Icore. Harry lives. |
| Secret Ending | Close the Loop | Requires specific dialogue choices with Dr. West in the future vision. |
To "Close the Loop" as instructed by the Great Engineer, you must realize that Dr. West is a future version of the consciousness transfer. Follow Harry's instructions exactly as they were laid out in the 1934 expedition notes.
Conclusion & FAQ
Completing the call of the elder gods walkthrough reveals a story of guilt, redemption, and the cyclical nature of time. Whether you chose to save the Professor or Eevee, the survival of the space-time continuum is ensured by the closure of the Yithian loop.
Q: What are the coordinates for the Yithian city?
The coordinates for Nakotus are 8-93-4-5, which Eevee remembers during her psychic vision in the Starry Wisdom building.
Q: How do I beat the Black Polyp in the Norway bunker?
You cannot kill it with weapons. You must use the control room panel to move the trap chamber and lock the creature inside the bunker.
Q: Is there a way to save both Harry and Eevee?
In the base game, the narrative requires one of them to enter the ooze pool to stop Bowen. However, the 'Close the Loop' achievement suggests their consciousness survives within the Elder God's Icore.
Q: What does the reverse piano sequence do?
Playing the notes in reverse order in the Virginia caves fills the tower with Black Ooze, allowing you to create the orb needed for the statue.
