1

Initial Setup

Examine the consoles, documents, and the chair in the icy chamber. Pull the switch to ensure Evangeline is seated in the chair, ready to interface with the machine.

2

Test Letter-Number Pairings

On the communication machine, systematically test different letter-number cable combinations. Observe the screen for matching brainwave patterns.

3

Identify Unique Brainwaves

For each letter group (A, B, C, D), identify one unique brainwave pattern that stands out or resonates.

4

Set the Dials

Based on your observations, set the four dials to the following combinations: A3, B1, C4, and D3.

5

Activate Communication

Turn the machine on and press the red button to initiate communication with the creature.

Observatory, Central Map, and Spaceship Console

After successfully communicating with the creature, you'll delve into a dreamlike ancient area, leading to the Observatory, Central Map, and eventually, a Spaceship Console. These interconnected puzzles require you to identify the correct time and place to travel.

Journal Reliance

Norah's journal is indispensable in this section. It contains crucial clues for solar system symbols, era representations, constellation notes, and the unique number system used by the ancient civilization. Keep it open and consult it frequently.
