AETHUS Inner Glow Quest: Facility Steps and Keycard Locations

The AETHUS inner glow quest requires players to investigate underground radiation by accessing Facility Lambda, clearing blocked sectors, and unlocking security doors across regional facilities. Progressing through the task involves crafting bypass moles, collecting keycards, and synchronizing terminals inside the undersea dam complex.

Quest Objectives and Radiation Investigation

The quest begins with instructions to clear down into Facility Lambda and isolate the origin of underground radiation. Completing this storyline assignment requires progressing across several abandoned corporate outposts to gather access codes and facility components.

Advancing through the stages also involves habitat construction at your surface outpost. An official hotfix corrected a tracking bug specifically for the objective to construct a Biology Lab, confirming that outpost laboratory infrastructure forms a required step within the broader taskline. Exploring the deeper subterranean routes toward Lambda brings players into contact with flooded infrastructure, damaged bulkheads, and the artificial intelligence entity known as Stanley near the undersea dam coordinates.

Crafting Bypass Moles and Field Equipment

Accessing sealed research sectors requires specific tools built at the electronics workbench. Dam systems store tracking strings that your drone companion Roland extracts from console units. Pairing these strings with electronic bypass devices known as moles allows you to spoof entry codes on reinforced bunker doors.

Each bunker entrance requires its own separate mole. Fabricating electronics and exploratory machinery requires refined base materials. Upgraded work requires refined items such as hardened glass and microcircuits, which depend on gathering raw minerals across regional deposits for players tracking down where to find gold. Servos are also necessary to repair stuck metal doors and drainage gates around the dam perimeter.

Keycard Locations Across Regional Facilities

Opening the central control area of the undersea dam requires collecting three paired keycards from separate facilities: Epsilon, Mu, and Theta.

In Facility Epsilon, take the route through the cargo storage area toward the Facility Control hallway. Injecting a bypass mole into the terminal opens the sealed bunker door. Inside the chamber sits a strange fuel rod enclosed in a dense ceramic casing alongside personal data slates. Search the personnel remains inside this bunker to retrieve Dr. Grant Harlo's keycard.

Facility Mu houses the local power generation infrastructure. In a Steam Community discussion on the quest, the developer confirmed that the secure door opposite the Mu bunker leads to the internal courtyard, while entering the bunker itself requires specific inventory preparation. Accessing the Mu bunker interior demands carrying a herbicide charge alongside a bypass mole to clear organic blockages. Entering this bunker allows you to secure Lisa Chapman's keycard.

Facility Theta focuses on bioengineering research, housing data that assists outpost cultivation through fixtures like the hydroponic bed. Tracking data acquired from the dam system registers the paired keycard required to complete the three-card set.

Undersea Dam Consoles and Remote Lockdowns

Once you possess all three keycards, return to the undersea dam control level. The main corridor contains three locked access doors that open only with their matching paired cards from Epsilon, Mu, and Theta.

Passing through all three security doors gives you access to the central dam console. To successfully operate this dam terminal and unlock remote commands across the grid, you must first interact with the primary console located inside Facility Lambda. Completing this interaction clears the remote lockouts affecting regional capacitor storage networks, allowing you to finalize the quest requirements.
