Call of the Elder Gods is a narrative-driven puzzle game where the two protagonists, Harry Everhart and Evangeline Drayton, explore the world to find an answer to their dreams and visions. The circumstances have led the duo to Spitzbergen, where they discover an underground bunker hidden beneath a radio station.

Table of contents
Frozen Bunker
While the duo is trying to escape from the Polyp, they end up trapped inside a frozen bunker. Here, they’ll find the Great Engineer frozen in ice. There’s also a spaceship nearby, but it’s locked for now.
If you look around, you won’t find much. However, there’s a chair-like device if you take the stairs to the elevated platform. This chair can be used to communicate with the Great Engineer.

Communication
Pull the lever on the device. As Evangeline sits on the chair, you’ll have to adjust the device accordingly to create a connection with the Great Engineer.
There are four knobs, an On and Off switch, and two indicators. One of the indicators is titled Untauglich, which means unsuitable. You’ll have to adjust the knobs until the green light lights up under the Geeignet indicator.

There’s also a screen on the left. There are letters and numbers on the lower half of the machine, and a plug to connect a letter to a number.
If you check each number for each letter, you’ll find that they generate different brainwaves with respect to Evangeline.

To make the machine work, you have to use the numbers and letters you get from the machine on the left, and put them in the machine to the right. To get it working, you’ll have to select the numbers and letters, with each one having a different frequency.
Use the following values for the knobs:
- A3
- B1
- C4
- D3
As you do that, turn the on switch and press the big red button on the machine. This will cause Evangeline to be teleported.

Pnakotus Of The Past
Evangeline will find herself in a dark place. Shortly after, the Dark Engineer will appear, and it’ll ask her to find the Pnakotus of her time, and it also tells her that she already knows the location, she just has to remember it.
Then, Evangeline will shift to a Yith’s body in the old Pnakotus. Here, you can find some notes. If you exit Evangeline’s room here, you’ll be able to make your way to the grand library.

However, on your way, you may encounter murals. Each of the murals in this area represents a different era. There are a total of 5 murals here.
There’s also the diagram of the solar system on the board inside the library. Once you’ve looked up everything in the area, go to the ray of light in the library.

This will take you to a gigantic device. The circular dials all around the machine represent planets. Check your journal and pick the third symbol from among the dials.

Now, the vertical bar on the machine can be used to select eras. Since you’re looking for Pnakotus based on Evangeline’s dreams, you have to remember the dream she had in the prologue.

The lizard-like animal you saw matches the image on the second mural, so set the vertical bar on the option with only two curved lines. Now, go to the back of the vertical bar, and here, you’ll find another C button.

Press it, and it will reveal the constellation that Evangeline used to see in her dreams. The constellation appears before another symbol. You have to memorize the symbol, but it will also be recorded in your journal.

Now, go down and exit the library. There’s a light path taking you to the observatory. There’s a machine on the bottom here.
Put the symbol of the constellation on this machine. You’ll have to rotate the dials and turn them around to get the desired symbol.

Now that you’ve got the symbol right, you have to type the number 5 in the Yithian language. It will require two curved lines, with a dot on the first line. We have to do this because Evangeline is looking for the coordinates of Pnakotus in the current era, the era of humans, which is the fifth era from the murals.
After you do that, the machine will immediately give you the coordinates: 8, 9, 3, 4, 5.
Evangeline will then return to the dark, where the Dark Engineer will ask her to take its spaceship to reach Pnakotus.

The Great Engineer’s Vessel
Once Evangeline returns to the present, you can then move towards the gate of the spaceship, which is just below. The gate will automatically open.
Step on the circular platform in the middle of the area, and the ship will power itself up.

There’s a device on the other end of the ship. You have to input the coordinates for Pnakotus here. Use the following image as a reference:

Once you’ve entered the numbers correctly and pressed the activation button, a steering wheel will pop up. Interact with it alongside Harry to make the spaceship start moving.

Future
As the ship starts moving, Harry will notice that Evangeline has lost consciousness. Evangeline will then wake up in the future.
She’s sitting on a mindswapping device. If you look around, you’ll find out that the year is 2006. There’s a brain-like device in the other room, with several plugs connected to it.

You have to experiment by connecting the plugs in different sockets to get the correct one. If you’re doing it right, the lights on both sides will be green.
Once you’ve got the correct combination and the device starts working, head to the chair. This will cause Evangeline to return to the present.

Dilemma
While Evangeline’s consciousness has traveled to the future, someone else has taken control over her. It’s Doctor West.
Doctor West warns Harry that he’ll have to sacrifice Evangeline to stop Bowen successfully. Once Evangeline returns to her body, you’ll have to choose to tell her the truth or lie to her. The Chapter will end after the conversation.
