The Map That Lost a Person
Three people left through the same service hatch. The route recorder shows three sets of footprints and three voices. The return register admits two bodies.
The map still draws a third figure at every turn. It appears as a blank space between the two confirmed routes, never as a mark that can be touched.
MOTHER ran the archive against every origin and human record. No match was found. The remaining crew remember a colleague but disagree about their face, name and reason for joining. The file is not classified as a Nullborn event; it is classified as an unresolved absence.
