AETHUS story and characters

Maeve is a former ARC mining engineer. She takes over a family claim with an AI drone named Roland and uncovers what an ARC survey team left behind, including a new element. The soundtrack calls that element Aetherium on track 15, The Aetherium Trigger. The spelling Athereum is a misspelling.

The store synopsis establishes Maeve, Roland and ARC. Public Steam achievement data establishes Stanley and the keycard names. More detailed plot connections are interpretations and are kept on the spoiler page. No personal gameplay experience is claimed.

Spoilers below. Open the story details when you are ready.

Story and progression details

Names the achievements print

Stanley is an AI. The Kappa Module achievement is about his nature, and Successfully Returned brings him to the outpost. Dr. Harlow's card is at Epsilon, Lisa Chapman's at Mu, Dr. Sinclair's at Theta. Buried Secrets is "discover the fate of Caleb Vihaan within Kryptos". That is the official spelling, not Vihan or Vhan. A Nintendo Everything reprint of the official overview names the themes as family, resistance, and choosing your own future. The planet name and the claim code AZ-1 are single-source.

Questions

Who voices Maeve and Roland?

Not published. Reviews mention Scottish accents and full voice acting. No cast list was on the official pages checked 28 October 2026.

What is Aetherium?

The name on soundtrack track 15. It is the element in the store's "new element" line. It is not a cryptocurrency, and one wiki's "Ethereum" spelling is a mistake.
