The Missing Hour

01 The case

Start with the part
that’s missing.

You are Mara Venn, a memory technician. When a father asks you to find his missing son, his last backup becomes your starting point: a gap of exactly one hour, and an image you cannot explain.

Follow the records, question the people behind them, and find out where the missing man went.

A story-led investigation.
Evidence, dialogue, and the people in between. Follow the case across three days in Néralis.

記録は、真実とは限らない。

02 Do the work

An image is a lead.
You still need proof.

Handle the evidence yourself, from the reader on a workshop bench to the documents in your casebook.

Meet the people behind the records.

Hear what the records leave out.

Ask about implants, invisible work and the help people give each other. Their interests can diverge, and an official record may not match the life behind it.

Get closer to the source.

Work the terminals, compare recording copies, and rebuild a sequence from documented events. Optional help and bypass keep the story moving.

A fact needs more than a feeling.

Examine objects and documents, cross-check your findings, and prepare a record that separates verifiable facts from private information.

03 Néralis, 2096

The towers hide the horizon.
Life goes on below.

Between the port and the canals, repair shops keep old readers running. Market stalls sell hot meals beside used prosthetics.

Two people meet at a canal-side café, with mechanical limbs, rain and concrete towers in the distance.

Beyond the case

Some things are worth stopping for.

A delivery robot still holds a parcel it could never deliver. Take an optional detour, follow its paper trail, and meet another part of Néralis.
